So I felt like doing some testing with a couple different radio versions and RIL settings to see if I actually did get any differences in speed or latency.
Phone is running CM6 Nightly 09192010. I did 8 tests on each state. Tests were done from 12a-1a so virtually no load on the network. After changing settings, I rebooted twice. All 8 speed tests were done by the SpeedTest.net app. I checked radio signal strength in Settings>About>Status and waited roughly 10 seconds for it to stabilize at the lowest value. I am located in Tempe, AZ. T-Mobile has not officially enabled HSPA+ but the download speeds reflect it. I hit 6.1mbps a couple times The phone was not moved at all for the entire process. To see the exact RIL settings I used, links are in the spreadsheet.
I have attached my excel file for ****s and giggles
Here are my results:

Green and positive means it was an increase with respect to the baseline. Red and negative means a decrease with respect to the baseline.
The "5.10 Error" is strange. I tried to flash 5.10 (see link in spreadsheet). It kept erroring in fastboot. Tried in recovery and it looked like it worked, but the bootloader was reporting 5.08. I did the tests anyway and I got different results which is strange.
In case you like numbers:
http://spreadsheets.google.com/ccc?key=0AmKcnlXnO3h6dExGSUlIdUtvSG56X2lvVHAwSlpSSlE&hl=en
PLEASE take these with a grain of salt! There are MANY variables I can not control that will affect signal strength, through put, etc. etc.
Also, one thing I noticed with 5.08U+Tweaks is the download was much more consistent. The standard deviation was much lower than the others.
Where are these radios of which you speak? (particularly 5.8+Tweaks)
Links are in the spreadsheet.
Since 5.10 is a desire radio, it won't flash unless you have a "PVT SHIP S-OFF" nexus.... those are usually engineering samples where the SPL allows you to flash literally ANYTHING...
This was discussed earlier in the 5.08 radio thread.... I'll try and find the exact posts when I get home later, but IIRC, the one person who was able to flash the desire radio did notice increased speeds.... but since its not quite the same phone AFAIK your chances of bricking the phone are exponentially higher....
That being said, phenomenal breakdown of the build.prop settings! I'll have to look around and see if I can contribute anything later, but great job!

Breakdown
Okay, found it here:
http://forum.xda-developers.com/showthread.php?t=723839&page=42&postcount=413
From that page forward is the discussion I was referring to earlier...sorry it's somewhat long, but I think they covered the desire radio question thoroughly there...
Okay, I apologize in advance for the following post, I know it's rather long-winded, so feel free to flame away if you disagree with anything I'm saying here or any of it is blatantly incorrect (I apologize if it is)
And these are just my thoughts and observations of what works for me, I'm not recommending you settle on anything here before figuring out what works for you...
OP, I'm sure you know this already based on your research here, but here's a breakdown of the "H" and "U" 'versions' of the radio for others who might be reading this thread and are interested in "tweaking the radio"
H - as in 32.36.00.28H_4.06.00.12_7 or 32.41.00.32H_5.08.00.04
Means that ro.ril.hsxpa = 1 (in the build.prop) is set, putting the radio in HSDPA mode rather than just plain old UMTS
U- as in 32.36.00.28U_4.06.00.12_7 or 32.41.00.32U_5.08.00.04
Means that ro.ril.hsxpa = 2 (in the build.prop) is set, which enables HSUPA
Now, not having these values set in build.prop doesn't necessarily mean that you won't get the HSDPA goodness (AFAIK AOSP ROMs are usually preset to hsxpa = 1 and Sense ROMs are usually preset to hsxpa = 2) because I believe that Android (or at least the radio) is hard-coded to jump up to the higher speed connection if available, but having these settings in build.prop just means that the phone will try making an HSDPA connection sooner than it would otherwise...
The OP has compiled an EXCELLENT breakdown of both speed tests/ping times/signal strength....that's outstanding work....
Sorry I'm making this post a little drawn out, and I'm not trying to hijack the thread here, but I'll share my 2 cents on what works for me if anyone is interested. Also, I apologize in advance for not having as much hard data as the OP, as these are merely my observations....
Ultimately, there is not one way of specifying these settings that will work for everyone....they are HIGHLY dependent on location, signal strength, radio version, ROM, service provider, number of applications running, clock speed, kernel type and version, maintenance on the cell towers.....etc....I could go on for a while here....
So what I'm trying to say here is that THERE IS NOT ONE SOLUTION THAT WILL WORK THE SAME FOR EVERYONE....
For reference, I'm living in Chicago, on T-Mobile, running eVIL's NXSense Desire Rom v1.20 with the network fix described in the second post (of that thread) applied (it replaces libhtc_ril.so and libhtc_acoustic.so because of connectivity issues when waking up the phone from standby, sorry, I don't know enough about how those executables work to give a better explanation) so I'm sure that makes a bit of a difference...
I'm also using the 4.06.00.12_7 radio (Official Froyo OTA), I tried the 5.08.00.04 radio for a while and I felt like it got slightly faster speeds and ping times (could be just placebo) but I ultimately switched back because it did seem to cause noticeably increased battery drain and my girlfriend repeatedly complained about my voice sounding "digitally mangled" during calls...
Though I agree with the OP's statement that the 5.08 radio did provide much more consistent speeds....with the 4.06 radio I've hit 5.2mbps (same situation with HSPA+, not officially turned on in Chicago) and then I'll be lucky if I can get 1mbps a couple tests later.... I did notice that ping times were also much more consistent with the 5.08 radio (usually around 90ms-160ms) and that unlike the 4.06 radio, did not usually require a "warm-up" test (usually the first speed test was garbage because the speed only kicked in about half-way through when radio/software/network realized that it needed to switch into HSDPA mode, this happens CONSIDERABLY more often with the 4.06 radio)
Okay, sorry, I don't mean to turn this into a discussion on radio versions....back on topic...
There seem to be some settings that work globally across both areas and providers, but most of what works well is limited to your location and your service provider.
It seems that setting ro.ril.gprsclass = 12 should work universally, from what I've read in other threads there hasn't been any negative reaction to this setting, as it just adjusts the number of GPRS timeslots requested by the phone. A quick glance at wikipedia reveals that UMTS (and by extension HSDPA) is still based on the GPRS core network, and while the nexus one's official specifications stated that it only supports GPRS class 10, I did notice a slight improvement with Class 12 set compared to without.
From what I've read during my time lurking on XDA, it seems that setting ro.ril.hsxpa is a bit of a mixed bag...some people are reporting that when it is set to = 1 they see dramatic differences in speed compared to = 2 or not being set at all....though some report that = 2 seems to work better and more quickly than = 1....like I said earlier, AOSP ROMs (Cyanogen, etc...) usually have it set to = 1, and that seems to work for most people using those particular ROMs....on the other hand, Sense ROMs (like any Desire Port) usually have it set to = 2, which also seems to work well for most users of those ROMs
What I've noticed when I have it set to ro.ril.hsxpa = 2, upload speeds seem to double from hsxpa = 1 regardless of location....
Also, these are not mentioned by the OP, but setting ro.ril.hsdpa.category = 8 and ro.ril.hsupa.category = 5 seem to increase the speed slightly from not having either set (look up "HSPA" on Wikipedia for more information on HSDPA/HSUPA categories and what they usually mean)
Since HSDPA category 8 is the highest speed the chipset in the nexus will support, there isn't really any reason to set it higher, though setting it lower could potentially increase speeds for those living in areas that haven't been upgraded to HSDPA 3.6 or 7.2... Same thing for HSUPA category 5, it's the highest the nexus will support, but not having it enabled would probably help in areas where your service provider has not enabled HSUPA...
Setting ro.telephony.default_network = 3 is the same thing as setting the preferred network type (in the *#*#4636#*#* testing menu) to GSM Auto (PRL), whereas setting it to = 0 would be the same as setting it to WCDMA Preferred....I'm not sure what setting 1 or 2 would do here, as this is just what I learned from my build.prop
Ever since I got my nexus I had it set to WCDMA Preferred, though when I switched to eVIL's NXSense about a month ago and found the default setting to be GSM Auto (PRL), I ran with it and it seems to be faster that way....or I'm at least getting less instances where it will randomly lose signal....but this could also be due to T-Mobile upgrading the network in the Chicago area (HSPA+ here we come! )
Okay, so that's about it....sorry again about that being so long winded, I just wanted to share what has been working for me and hopefully clear up any confusion for those reading this thread....
I'm sure there's some things I've left out of this or stated incorrectly, it wasn't meant to be exhaustive or authoritative, just merely my observations on the matter....
And thanks again for the OP for starting this topic and putting up their findings in spreadsheet form (I'm a statistics geek ) it is very well compiled and organized....I hope I didn't clutter up the thread too much here....
Radio Interface Description
If anyone is interested, I found a more detailed explanation (from Google themselves!) on how the Radio Stack works...
http://source.android.com/porting/telephony.html
It gets into technical details that are a little over my head and it doesn't have a ton of information in regards to what is in question here, but I think it is still somewhat relevant and, if you have time, is a very informative read...
I'm not so concerned with blaaazing speed, as I am with sensitivity of the radio. I need reception in outlying areas, and I suspect this would help with speed as well, getting HSDPA sooner.

I was using my phone on my wifi connection earlier today, and I noticed in the Networks dialog there's a bunch of wifi connections already there (but I've not used the phone in town, and I've never even seen some of these wifi hotspot names before), so that got me thinking...
... Does the fact that I'm subscribed to Web 'n Walk as part of my tariff mean that I also have free access to any of the hotspots predefined in the list on my wifi networks screen?
Here's the full list:

Anybody have the faintest clue as to why these are already in my wifi networks list?
Yeah, I've got an idea. It's 2nd hand or ex-display. considering no-one else has reported having these hot-spots pre-configured on their Vario2s, it seems logical or at least likely that the device has been used before.
i.e. returned under the 14 day guarantee that if not satisfied with the product, they'll take it back and squash the contract. look under 'device information' and then call duration. If the call duration exceeds your actual usage, then that prooves it. If however it matches your call usage (see you call history), then maybe just maybe, T-Mobile have introduced this to their extended ROM in newer devices, but I doubt it.
All calls: 27min, 30sec.
This about tallies with the amount of calls I've made (mainly to customer services to get stuff like HSDPA set up) and a query about my account, plus a call to my Dad and a couple of mates...
I did notice during the customisation process that there was a cab containing 'June 2006' in its filename... Here's my ROM and hw stats:
ROM: 1.21.110.3
ROM date: 06/19/06
Radio: 1.05.05.00
Protocol ver: 32.36.7010.04H
My boot screen shows (in red)
M05
S04
B06
D1.21
at the lower left of the screen, and then my Radio and ROM versions show up fleetingly before the device shows the Windows Mobile splash screen. The device also had its protective screen cover on, which I had to peel off - and didn't look like the screen had been touched or used. Of course, they could clean it...
... I don't think this was a refurb though. Course, I could be wrong. I suppose I'll have to go find a wifi hotspot, or maybe ring up T-Mobile cust. services and ask :/
My Vario II also has lots of preconfigured wifi networks on it.
When I received the phone I did check the calls in/out and they were both 0 mins and the phone was immaculate (no scratches, fingerprints etc..) so I would be surprised if it was a return.
I have no idea if these wifi settings relate to free hotspots though or whether you would still have to buy a wifi key if you happened to be in range of one of them. I will give it a go next time I am in a larger town, where I live I don't think there are any public wifi hotspots.
I'm in Brum, so I'll go check it out (there's a T-Mobile hotspot in the bar just outside my uni building, which is actually a student bar too, so I'll have just go and have a couple of pints and investimagate
yeah, mine had all those preconfigured too. think it's standard.

Wow. Very interesting indeed. I'm glad to be wrong. I wonder what else you and the other guys have in your extended ROMs as this does indeed seem to be a part of Your ROM. Please let us know how you got on with the Hotspots investigation and beers.
My Vario2 came pre-loaded with eleventy million different wi-fi profiles and wondered about free hot-spot access myself but when I tried to access the hot spot at my local Starbucks it still asked me for a log on I'd & password - I tried the log on I have for My T-Mobile but it came back as invalid. My guess is you have to subscribe to hot spot access seperately.
I just noticed in my Programs list I have an Interactive menu (with the T Mobile logo superimposed over a picture of a SIM card)... Clicking it goes into an app called 'STK Service', which gives me an interactive menu.
I have the usual, Fun, Info, Music, Chat, Sports, Games, Text plus, Groups, Voicemail, t-zones (oh aye?) and Prepay topup...
So I click on t-zones, it shows a white screen with the text 't-zones' on it, and the soft keys turn into Yes and No. I click Yes, and it opens IE with a weird URL (all boxes, so in a character set I can't discern), then WM5 shows a dialog box with "Cannot connect with current connection settings. TO change your connection settings, tap Settings."
The plot thickens...
I have all of those access points as well. And mine is a brand new Vario II.
I emailed T-Mobile a while back asking this, and the other week I got a response:
Ross @ T-Mobile said:
Hi Christopher,
Thank you for your email about Wifi on your MDA.
The profiles on you phone are mostly T-Mobile related, there are some which are for T-Mobile in other countries, BT is also there as we have an agreement with them. The others are just large Wifi providers.
They are put on the phone just to make it easier for you to connect to them. They are not essential in any way to making your phone work and if you want to delete them it will not cause any problems.
I hope this answers your question, if you have any further queries please don't hesitate to contact us again.
Kind regards

Just a bit of preferential configuration on their part Only takes a minute to remove though, so it's ok.
I have the exact same pre-configured Wifi profiles on mine. I just deleted them.
me2
Yeah, I got a response a while back from T-Mobile - they are purely 'to help you connect to one of our hotspots more easily' for want of a better way of putting it.
I did a more custom install this time round when I got my replacement Hermes, and didn't install the CAB which sets up the access point SSIDs in the Wifi Network profiles... They now don't appear.
The TM rep confirmed that I didn't have access to the networks, they were just there as, effectively, shortcuts.
Not true

Mine was brand new and sealed and came like this. There is another thread about it somewhere as I remember seeing it - it definately doesn;t mean it isn't new.
Totally brand-new Vario - and these (useful) profiles were included.
If you use BT's Total Broadband package (as I do) then you will have 500 free OpenZone minutes to use every month (something they do not advertise very much).

No, it's so not true. I broke the security seal on the package. There was not a single finger mark or anything, you don't need to be a genius to tell if a phone is ex-display or 2nd hand.
I've recently bought the HD2, former I ownt the TyTn II and th XDAII
Now I want to turn off the HSDPA data connection (The "H" icon appears in the taskbar) I only want to hav a "normal" 3G connection!
Can somebody help me to finnd the switch in the settings to do this!?
Cheers Chris
Why would you want to ruin your cellular data connection?
Connections > Advanced network...disable HSPA. Soft-reset.

1) If you're in an area with low to nonexistent HSPA, having it on will drain your battery immensely as it searches for signal as you're surfing.
2) Similar to #1, using EDGE or 3G will reduce battery consumption because data pulling will be less intensive.
3) if you're not doing a lot of streaming and only use your phone to read websites and/or update stock/weather/twitter/fb/etc, having it on EDGE or 3G produce similar results.
I can't believe I'm listing the options as to why the original poster would want to limit his data to just 3G, but I guess I shouldn't give too much credit to the kind of people who post on this forum.
HSDPA - isn't it working only under umts? I have EU HD2 - GSM model, should I turn it off permanently?

uhh what? Do you have an "H" symbol on your HD2? If not, then there's nothing you should be worried about.
nor really an bump but
HSDPA is not very reliable once single levels get below 100/95dbm (or 2 bars some times 3 as it does not always update in real time)
other note if H is enabled the phone will waste time trying to connect to an H signal that's not there or mite just be in range but is not
on my HTC HD1 the phone works 95% of the time with UMTS basic 3g some calls are diverted, but with HSDPA it sucks more power and more of my phone calls get diverted on an daily basis (diverts to my other network phone when phone not connectible, not stating networks as its the phones Fault for connecting to an H or 3g when it should be on stepping down to 3g then 2g due to signal) norm as i use my phone for business use i leave the phone on 2g only so (my other phone that's an htc desire i norm do use the h on it as it tends to play nice and drop to 2g when it should normally)
any way my phone is not the issue as i have the benefit to disable H speed and use 3g (umts) on the htc hd1
i have the hd2 phone here right now but the phone keeps on insisting to stay on H when single levels are poor and resulting in txt'ing only working , forcing the phone onto 2g fix's the problem but norm 3g coverage is fine
is there any way to turn off H on the hd2 like the hd1 can or is there custom firmware that adds the option or adjusts it so its less aggressive
don't know why we are bringing this up from the dead, but I get great download speeds with only 1-2 bars of hspa (+). I can't see why I would want to turn that off.
And to the poster that says edge works fine for most things, most of my updates time out trying to update on edge.

i hate edge.
the thread was never answered correctly (users posting on how good H is over 3g but from where i am its not so good as its turning the hd2/1 into an iphone 3 dropping calls wise when 3g/H is enabled) also turns the phone into an oven compared to umts mode and phone only lasts about an day with H enabled (2-3 days UMTS, 3-5 days 2g/GPRS depending on use)
3g?UMTS {most reliable for 3g} > HSDPA > HSUPA think there is an H+ as well for 7.5mb support
2g> gsm/gprs is king for keeping signal levels (EDGE unknown as I never get it but should be the same as GPRS) as there are more 2g towers then 3g or 3g/H towers, not cost affective to upgrade them all to 3g
one thing i not done yet is update the phones firmware as its still running on an 1-2 year old os this HD2 (uk t-mobile), the radio on it is 2.04 as well (my HD1 is 2 years or older) some one did post that it is in settings > adv network {was an older post that i found on google} that is missing on this currant HD2 phone i have
Most of the UK networks have not upgraded to edge around where I am so its GPRS or 3g/H
Some ROMs have the Advanced Network control panel applet in Settings/Connections where you can disable HSDPA and HSUPA.

I believe the relevant registry setting is at registry key HKLM\Software\OEM\RIL - DisH (Where a value of 0 disables HSDPA/HSUPA, 1 enables HSDPA and 2 enable HSDPA/HSUPA, reboot needed)
That was very useful comment I try it when I get back home later on (should really update the firmware as well the HTC touch flow is quite unstable on it)
i dont know where the problem is.
start -> settings -> connections -> advanced network.
there u can choose "disable hsdpa / hsupa"
bling, u got no H anymore..
if u use sense, u have to go via the windows settings, u cant change that in sense settings tab i think

i have to ring him on his G1 phone, if i ring the HD2 i get 2 things that happen its not connect (5 secs then the peeps call not conencted) or he answers it and it disconnects after 2 seconds
mite flash the device i never done it my self so mite do it on my HD1 first as mine is running on winmobile 6.2
--------------
i use an blackberry 8520 as an test at this time, was only £100 for it but i am missing the touch screen but like the idea of the 9800 having both screen and slide out pad but i prefer the windows phones input calendar points (hoping the win7 way be the same or like it)
that seems to have worked, did not seem to take it on the first reboot,was set to gsm only, set to auto was doing H still, still set to auto and powered down again and pulled the bat (prob did not need to) no h any more phone has constant 2-4 bars now on 3g (before 1-2 bar or drop call, on H if the phone was picked up 4 bars idle) can use phone and internet (was an fast call test was stable an clear not breaking up) should also stop it turning into an oven as well (as my HD1 does with H enabled), 3g is fine with opera as it has the turbo feature so web pages load fast still
give you rep if i could
i am not new to these forums but i have not done any messing with rom as my HTC HD1 one is currently just an unused PDA so i will have an go with it just need to look at the updating guides (need some class 6 sd cards as well all the ones i got are class 2 and are bit slow) if
once i have played with my hd1 i update the HD2 as that is an active phone (but needs updating on both phones as the default htc touch flow is an bit of an ram or cpu hog making the phone unstable, i disabled the touch flow on my hd1 as preventing phone call answer from working after 2-3 days as i needed it for business use but i like the default windows mobile layout anyway but i also like the htc layout when it works but must work all the time)
Right. You might remember I had connection issues with the HD2. I sent it off for repair, and it came back, but now displaying "3G+" at the top. This was super fast and everything was working fine. Now, all of a sudden it has gone back to 3G that is REALLY slow! Now, I see other people are having this problem. According to Vodafone, I am in a 3G blackspot and there is nothing I can do. If this was the case, I would never receive 3G+ in the first place, which they just ignore when I ask them about it. Could it possibly be the phone? I personally think Vodafone are just messing me around
Only 1 view? Any reply would be appreciated, this is an ongoing problem for me...
Edited : Was being a fool
Just because people look at it it doesn't mean they are going to have an answer i have seen some threads on here go unanswered for the best part of the day until someone comes on-line that actually has an answer, so just give it time, not every member knows what everybody else knows, that's why its a forum for people to club together and help each other out.
rant over
Oh ok, I'm sorry
Ok, so now Vodafone are ignoring me, which is just great (pfft). I would appreciate ANY help if there are any tips as to any procedures I could undertake. The HSDPA I was receiving just cut out the other night, and won't budge from 3G any more, not even to G or E, which is kinda annoying.
Have you tried it in a different area? You'll not get HSDPA coverage everywhere - that's normal. The way you're talking, seems like you're just sitting in your house testing it.
Of course I've tested it elsewhere. What you need to understand is though, I was receiving HSDPA full in my house for a good few days after I got the phone back from repair, now its just gone. All of a sudden, gone. I try doing the network selection process again, and the 3G+ flickers for a millisecond at the most, and then disappears. I don't know why this is happening, I used to get brilliant HSDPA connection wherever I went in Preston
Just to give you guys a glimpse of EXACTLY how bad the connection is, I ran a speed test on my phone via speedtest.net. Here are the results:

What is wrong? that you're getting as-expected 3G speed (.38mbps is the equivalent of 384kbps 3G standard) or the fact that you're getting a 3G+ symbol but are only getting 3G speed? Just because it's showing 3G+ (im assuming that it's similar to HSPA) doesnt mean you're at the optimal cell distance to receive it. It may be VERY POOR in your case, so it bounce you down to 3G.
That's the thing, its not poor in my area. I mean, I don't think even standard 3G is as slow as I'm experiencing. A 12 second YouTube video taking a minute to buffer? www.google.com taking a LONG time to load, there's something wrong man. I feel like just selling this phone and getting a BB or something, I know the connectivity will be strong with that.

How do you verify? Do you have another vodafone nearby that you can test out?
That's the annoying thing, I can't test out my SIM in another smartphone, as this is the only one I have. I have however tried another SIM in my phone and there is the same problem. This is the reply I get from Vodafone eForum:
Hi Faz20,
If it was a site fault that was to blame for this before, then it's highly likely to be the same sort of problem again. Issues like this are rarely ever the fault of the handset.
I have checked the postcode listed in your profile, and can see there are three possible HSDPA sites around you, none of which are showing any open faults at this moment, so we'll need to raise a case to our Faults Team for this to be investigated further.
I've emailed you so that we can start this process off

What is annoying me is that they keep ignoring me when I say I was experiencing fine internet connection with smooth speeds, and it just suddenly cut out. They just change the subject ALL the time when I mention it :angry:
One more to remember: you have to consider the speed AND QoS as well.
Try another site, I'd google for visualvare my speed.
If you have poor quality of service (you have veeeery long ping) that means: your phone tries to download.. then waits.. then tries again.. and some packets are lost.... so tries again... and so on.
1699ms ping is quite a lot I imagine? As my puter is only like 0.6ms, but surely the phone can't have that big a difference. Is there anything I could do to lower the ping, I don't want to flash and cooked ROM's atm as I am very inexperienced and don't want to void the warranty.

Then you're simply in a 3G blackspot. I know it's disheartening for having an HD2 and stuck with ****ty data coverage, but that's what seem to be the problem right now. You have a seriously high ping coupled that with slow transfer speed would only dictate that you're not in an ideal area where 3G coverage is plentiful.
How would that explain that I was receiving fine connection speeds before? This is where my hair is falling out

Maybe you're hallucinating that you had fast connection before? Maybe Vodafone thought that your area doesn't deserve the bandwidth and thus prioritizing the 3G speed for other, more robust, cities? Or maybe radioactive termites have run amok on the cell tower, causing you to not get fast 3G speed?
Who knows...
Nah, I can assure you I wasn't hallucinating, I stay away from the Magic Mushrooms
I just think Vodafone are a bag of s*it. All my friends with the same phone on O2, Orange are receiving HSDPA all the time. Its stupid
I'm gonna phone up Vodafone today and kinda go mad at them. The last time I phone they "escalated" the connection, maybe the reason why I was getting HSDPA all the time, wherever I went. Now suddenly its gone again. Quick question for you guys, when your phone is on 3G Full bars, how is the speeds. Are they quick and rapid? Do Internet pages load quickly? etc. etc.
Ok, so what do I get told when I ring up Vodafone. I have bad 3G coverage in my area (blatant lie). When I ask how do I resolve this? Buy Vodafone Sure Signal, £50 one off payment or £5 a month. Great way to resolve a problem, try to sell me something else, another one of Vodafone's probably bullsh*t products. Its so frustrating, having to live with a stupid network provider with such a beautiful phone!
Can I cry on someone's shoulder?
how fast are you guys get from the tmobile internet option?

please tell me what radios you guys are using to get such good 3G speed.
I curently run android on my leo and even tho i got h indicator in my area i barely can go above 1mb/s down. I didnt test it on windows tho.
I use stock tmo radio
Just did a test with a speedtest app
1.58 down
0.8 up.
Sent from my HTC HD2 using XDA App
are you serious? how is it other phone can go up as far as 8MB and we can barely get 1?!

Hold on there. First, the android builds that can run on this phone are known to get slow 3G speeds no matter what, compared to what they should be in that location. nomadwgk would get a considerably higher speed if he was testing it through winmo.
Now, your speeds don't look right, if you're in a well-covered part of the DC area. This phone can indeed get speeds all the way up to the 7.2Mb limit, I've had mine test that fast once or twice here in bursts, but I usually get around 3-5Mb avg. So, there's something preventing your phone from getting the speeds it should.
Has it always been this slow since you first got it? How many bars are you seeing when you test it? What method are you using to test the speed exactly? This info will help us troubleshoot.
Plus, how strong of a signal did you have? From what I gather, a 4 bar signal will outperform a 2 bar signal.
i don't know how you guys get such a fast connection. every time i test it using dslreports i only get about 100-130 kbs. on a 400k test. and that's on a strong 3G connection in the middle of the city.
Its says my RR Turbo gives me 339 kbit/sec 1MB test. wifi connections on android, :::checking windows::::

There's a couple of factors at play here...first, you'll probably want to test with another site that uses a larger test file. I recommend www.speakeasy.net/speedtest...it works in IE but not opera, but it's the best mobile test site I've found.
Second, I learned from a T-Mobile engineer recently that the HSDPA speeds are actually dynamic, and load-dependent. In other words, the higher speeds won't fully kick in until you're transferring a larger amount of data at once...otherwise you'll get regular 3G speeds (or less) while just pushing a small amount of data (like weather updates, etc). So, you may not be able to measure the full speed you can get, until you're transferring a large enough file. That site I mentioned above seems to use a big enuogh test file to get full-speed results from the network.
Same problem
i live in vegas by the strip so OF course its gunna be good service,
I have 4 bars on "H" some times it will change to "3g" but it will still have 4bars... and my internet speed is like not even close to a MB, i took your advice about higher file transfer so i hooked up my xbox to my internet through my phone it worked, but it was really SLOW!
how can i fix the internet speed.

i'm not using android OS man i'm using the latest energy rom, you got any good radio to reccomend me? i'm using 2.12.50.02 radio and constantly getting that H instead of 3G wth and its about 4 H bar most of the time but sometimes 3G coming in and out.

I didn't assume you were using android, I was just letting you know his results definitely weren't indicative of what the phone is capable of.
I use the radio you'll see in my signature below, it may make a difference, I don't know...it's the only one I've ever used on this phone.
You might want to double-check these three things:
1) Go to settings (WM settings, not Sense settings), and in the "connections" folder, choose "advanced network". Make sure "Enable HSDPA/HSUPA" is selected on the first tab there.
2) Also in the connections folder, choose the "connections" icon. Choose "manage existing connections" under the "T-Mobile Data" heading. On the "Modem" tab, make sure the T-Mobile Data connection shows "epc.tmobile.com" under the "Number" header.
3) On the Proxy Settings tab there, make sure "This network uses a proxy server..." is unchecked.
Good day every one
Really long time ago I had an idea! But few other people had the same idea Other projects use WIFI for a connection but I am talking about actual cellular network (GSM).
The idea is: add a feature to an open source cell phone to be able to make calls without a network provider. The design will look like a computer mesh network.

Think of every cellphone like a Cisco network router with dynamic routing enabled.
Each phone will be aware of the presence of other phones and will have route table to every single one. There is no centralized server sort of like peer to peer.
When a user wants to make a call, then the cellphone will display the devices that are online and can be reached.
Look at the picture above and notice that there are more than one route to each device. Having many phones like that will increase the coverage!
Now does anyone know how to implement a such thing?
Maybe use android phones? Since OS is open source maybe it is possible to add this into it?
What do you think?

I dont think its practically feasible..
And moreover You cant use Service Provider's cellular network just like that ( and that also free)
man u realy want to learn how cdma, gsm,edge,2-4.5 g networkz work. and whatz a mobile handset realy do when its connected to a network.
send from my hd2 @ dorimanx v.3.0.0.rom,with 2way rec kernal.
I think Serval Mesh is what you want
EDIT : oups, already in your list...

The idea here is to create an independant cellular network, using only the GSM equipment of phones, without using the service provider network.
sounds like a great idea, i would want something like this for sure. but the only down side is that you could only make a call for as far as the network broad casts which means in a small town it would really suck.
Nice idea but very costly.
Sent from my Galaxy Ace using Tapatalk
That's an interesting concept, but from what I understand, to make a call without an operator, both phones will have to be connected to the mesh network, right?
That situation would be rather rare, it's like making a video call between two iPod touch (that don't have a cellular network). If the other side is not connected to WiFi at the moment, the call won't go through.
Also something to think about is the battery life. If other people's calls would be routed through your phone all the time, it would drain the battery very fast.
The unfortunate bit to this idea is that, barring hardware,privacy, and feasibility constraints...If you implemented such a network, there would be no guarantee that you would be within the bounds of the network at any time. With current providers, there are rough estimates as to the coverage area that are fairly accurate, depending on exact conditions.
With this system, if a couple people in your neighborhood leave the town or country, suddenly, you have no service, or slow service.
It'd just fluctuate too much and wouldn't be reliable.
Phones hardware and closed-source software isn't designed to ad-hoc networking. IMO the closest available solution for that is this:
http://openbsc.osmocom.org/trac/
It is definitely an interesting idea, sorta makes me thing of "Ad-Hoc Networking for Phones". The only problem is, the phones would be limited to calls in their "network", so if you had 3 people in a desert, they could call each-other, but would be otherwise sunk
The problem though lies in that it would basically use your phone to power everyone else's phone service, and that would mean that your precious phone would be crunching data all day long, and eating batteries like they are going out of style (Not that it doesn't already).
So while in-theory you could get cellphones to all link up in a row and make a cell-to-cell network, latency would increase exponentially the more phones you have to "hop", and battery life would decrease.
Good thinking, but you would be better off starting your own cell network, and not charge outrageous prices. I am sure that we would all be happy to switch if you had good coverage and reasonable service
Nice idea hoping network providers would agree to implement such network feature.
But on the other side, it's far way impossible. For sure network providers would not allow that because it's some sort of a hacking over there frequency.
Not like Walkie-Talkies or CB Radios (Civilian Band Radios) where they operate at there own frequency with there own cell site for CB Radios.
I think the only way to make it possible is to hack the phones frequency and make it adjustable and add a unique ID for each phone. i.e. just like how the SIM Cards work. Once the frequency is hacked, then it is possible to control the transmitter.
Anyway, this is just my own IDEA, correct me if im wrong.
Nice idea,
How about openBTS ..? openbts,sourceforge,net
what different..?
I really have been thinking anout the same thing.somehow its gonna crack.
neat idea. although i agree with above posts,
battery would be an issue.
what if someones phone dies?
also, i see privacy being an issue. sure you could encrypt the call or text, but you would have direct access to every device in between point a and b. what would stop some smart guy from finding a way to invade your device. or write some malware that would run across the mesh. maybe i don't understand mesh networks well but it seems like a concern that would be valid.
biggest issue i can see is reliability. there are way to many variables for this to work out of heavily populated areas.
some kind of closed demonstration would be cool though
The problem with this is the modem/radio firmware is closed. It would be totally possible if we can get proper source for the modem/radio for each targeted device.
The battery drain would be tremendous. however this may be implemented in the form of an app or a function in android which can be switched off when not needed. This would also address the network congestion issues in crowded places. The more handsets the better.
It's an interesting idea, but has limits
If we thought about creating a new phone for this new network so that we weren't restricted by current cellular standards or architecture, it could be a good idea. The number of clients that the network could support via RF would be limited, however, because of the amount of signalling necessary between peers in a P2P environment and the fact that RF is broadcast, not point-to-point. Therefore, in order for peers to be able to hear each other over a reasonable distance, there would need to be a limit on the density of the mesh's population. In the current cellular topology, this limit is quite high because each handset only needs to communicate with one tower at any one time. In a mesh topology, each handset would have to communicate with a bunch of others in order to maintain the mesh and do the work of moving data through it.
So, this sort of topology is well-suited for low-density environments, but not so low-density that a handset can't communicate with at least a couple of other handsets. Also, at least one of the handsets would need to be able to communicate with a base station so that the whole mesh has access to the global comms network.
It's possible.. but impractical in a few cases.
I could understand in a densely populated city.
But what would the effects have on the radio usage?
"there by also the effects on battery life"
You'll find a nice video introduction into creating your own GSM network when Googling "CCC gsm network" and look at the 3rd link (I'm not allowed to post outside links). This should allow you to understand some of the GSM related technical terms on the OpenBSC page. I'm not sure if the guys from the video are the same people running OpenBSC.
I think that VoIP would be more interesting for you. Since it's really easy (NAT-ing can be nasty if you use multiple clients) to implement and you can use it over WiFi (generally internet).
So you could install a VoIP server at home accepting phone calls and forward the calls first to your mobile phone via WiFi when the phone is connected to your WiFi, otherwise the call can be forwarded via WiFi. You should even be able to use your VoIP Server at home to forward a call from your mobile phone over the internet to another phone number.
I think this is one of those pie in the sky ideas. While it sounds great there are some huge challenges. First and foremost the radio in your cell phone is locked down and you don't have the access that you need to be able to do that. The second issue is security. Routing voice would be fine but routing data, you pretty much have the worlds easiest man in the middle attack. The third issue is spectrum. Cell phones use RF spectrum that is bought and paid for, as in we can't use it otherwise the FCC could fine us lots and lots of cash money. And like others have said battery life would be awful.
I think there is a potential solution here though. Purpose built hardware. I know that some of the Ham bands are pretty close to the cell phone bands (close enough to work with cell phones). We could design a piece of hardware to act as a tower and we could start our own network. Using the internet as a backbone.
