Streaming audio --> GPRS/Edge speeds, T-mobile USA

Great forum,
I was wondering if anyone else is able to stream shoutcast or similar in the US using the kjam? In the denver area, I can barely stream 56Kbit streams, as they have to buffer all the time. Occasionally I can stream a 128Kbit stream for an hour or more. I upgraded my 6315 ipaq (among other reasons) to make use of the supposed Edge data rates.
I have tried GSPlayer, TCMP, Resco Radio, and others. None of the prebuffering options seem to help significantly. It seems logical to me that even over GPRS speeds, I should be able to buffer enough that it should only hiccup once a .5 hour or so. Resco Radio seems to work the best, yet it has the least buffer tweak options.
Any advise?
Thanks!

Interested int this too. Just discovered Shoutcast today and I'm in love, but the pauses/speed is irritating. Any fixes?

Well...I've noticed something concerning streaming audio to my device (Cingular 8125) over EDGE. Unless I use the 'dialup' servers it won't work. I decided to do a speed test at bandwithplace.com and I discovered that even in places where I had 4 full bars and complete EDGE coverage I still only got results of about 100 kbps +/- 10kbps. So I've been somewhat limited in where I can listen to most streams. Imagine my surprise when I learned (today searching that same website) that EDGE is actually rated for 384 kbps! If my home broadband service (rated at 6 mbps) suddenly only worked at 2mbps I'd be angry. Well after venting a bit, does anyone here know if this speed is a limitation of the hardware/software or a bottleneck in the network itself?

I don't know much about the technical issues but my understanding is that EDGE works using multiple channels or timeslots which aggregated together would give you the theoretical maximum of 384. If the network you are connected to has much voice traffic then voice channels take priority and the slots available to your data would reduce and consequently the throughput. There is also the potential that a network may not allocate the full EDGE service but throttle the number of channels available to you on the system giving you a lower maximum rate evn when the network is fully available.

So far my experiences have been such that I have given up on streaming audio through my kjam over EGDE. From an email or browsing perspective GPRS seemed just as fast, although the speed tests seemed to indicate a higher throughput. It's a good thing the Tmo in Denver Isn't charging more for EDGE over GPRS or I'd be angry!

My experience has been that using Orb I can stream video from my home PC with little problem other than the occassional pause (makes those long meetings tolerable ;-)

Update:
I was using Shoutcast thru TCPMP again and this time, I seemed to be getting a better GPRS signal, resulting in a stream of music (same station as before) that lasted about 10 minutes without a hiccup, and then about another 10 more without another break. It was fantastic! Using shoutcast thru TCPMP has been the best experience I've had with internet radio to this point....

I love my Wiz now, but why is it so lame 'out of the box'?

I love my MDA more and more now. But after my first week or two i was begining to think i had made a mistake buying it. Thanks to the kind and helpful folk around here and other forums, i now have it doing everything i wanted it to do and in the way i want it to do it.
I use it for TomTom, playing DIXed DVD's, music, podcasts, games, the usual email/web duties and more. And thanks to the great WiFi 'G' reg hack i can now stream my large lossles FLAC files (with the help of fantasitc Conduits Pocket Player) right into my Hifi system, just like my Squeezebox 3 media player. It's actually much better than an ipod (albeit with less storage when out of the house - although i could access my music at home from a hotspot). A fully fledged media streaming device for free! (well, a small fee for Pocket Player and a 2.5mm to 3.5mm jack adaptor).
Not only does this hack also enable 'g' speeds, but i can confirm that it also massively increases performance on 'b' speed networks too (which mine is limited to due to being an 'adhok' network).
Sure, a faster proc, better camera and maybe even 3G would be nice. But i have no wish to ever make video calls or use Skype (i'm the geek of the group and no-one else i know uses it).
I understand there will always be better third party software (Media Player is an utter waste of space for example) but why should we have to make techy and annoying tweaks to the registry, just to get the best from the unit? Why the hell do we need to hack the reg just to make a basic settings change, such as hiding SIM contacts (which is an option in just about every mobile from the last 5 years).
Is it just bad planning? Poor thinking on the manufactures part? or is there just a genuine reason for 'hiding' these settings and not making them accessable from standard menu's?
The older i get, the less time i have to mess around so much. I have better things to do these days to be honest.
Surely they would have more to gain by activating the performance increases themselfs, rather than us more tech savy types to figure out how to alter the registry. Half the things this device has been slated for in reviews can actually be sorted, but the average (make that normal) buyers of this device will be feeling a bit short changed if you ask me.
I guess the only thing left for me to do now is dump the T-Mobile ROM and use a more slimline one. Or maybe i should just figure out who to lose some of the crap from my existing install?
What is it with these companies? Don't they know when they are on to a good thing? Or maybe, just maybe it to keep us coming back for more and upgrading year after year? Hey ho...
/rant over.

Dom
Very interesting topic, well put and one which I'm sure will be relevant to me very soon...y'see my Wizard arrives in two days and it was reading posts such as yours which helped me take the plunge.
I don't mind messing about with PDAs, phones, PCs etc to get the the best performance but (as you rightly point out) we shouldn't have to. However, given the thousand of threads and posts on this (incredibly good) site, I am somewhat confused about what to do first with my Wizard.
So, could you please take a few minutes to post what changes, hacks etc you have done to get yours where you (almost) want it to be?
Many thanks in advance.

The first things i would always do after a hard reset (format), after syncing back all my contacts/callender of course...
Reg hacks (main ones, i have forgot a few) -
*Hide SIM contacts (so the dont appear pointlessly twice)
*Enable 'g' speed Wifi
* Disable the annoying 'you are about to go online' message. You will understand when you get yours, VERY VERY annoying - you get it even when you are online and just switch back to PIE.
* There are some good performace tweaks to, which i forgot about.
Essential software i could not be without (some free, some not - unless you are naughty. Don't be naughty now )
*TomTom (Sat Nav)
*Memory Map Pocket Nav + GPS and the O.S. maps i use for walking
*TCPMP - The best video player
* Conduits Pocket Player - the best music player IMO (Streaming, gapless playback and OGG/FLAC support - nice). costs a few beer tokens, but free good alternatives are available.
*Resco File explorer and Reg editor.
*Opera Browser - Renders pages faster than PIE, handles java script etc better and Tabbed browsing makes GPRS speeds much less of a pain.
*Memmaid - for cleaing up temp files, dead registry entries etc.
*Storage tools - for formating and sorting out MiniSD cards - WM5 can't even format a bloody memory card!
*Wififofum - for finding WiFi networks (more for fun than anything).
*OMAPclock - for a bit of overclocking (more for fun again, i rarely feel the need is that great)
*And of course registry wizard for the good people of these forums
Thats about it really for me, but i am finding more cools things everyday to play with but those are my must have ones - i have had to install
A few must have games include, AOE, UFO, 3D pool and Soduko.
Personally i dont use a today plugin. I have not found one i like yet and most have icons etc that are to small on the MDA's small screen or just make clutter rather than really help me. A well organised start menu is enough for me.

Oh, and of course you can flash the ROM. But i have not done this yet. T-Mobiles version does not seem that bad but i hear the O2 version is a real dog and well worth doing. I just worry about lost Wifi and GPRS functionality i have heard about some people having.

Really wasn't expecting a reply so soon, and certainly not such a comprehensive one. Thanks for your time. I may be back with more questions once I actually get my mitts on a Wizard. Cheers!

yes I agree , it is great post, specially for new people like me, I got mine (Qtek 9100) just on Friday, and I am still figuring out its functions.
But I have question - if you have time to answer - I really don't know about WiFi function -which is in the device- , if I want to connect to the internet I should have a wireless router connected to my main PC, is that right ? I have read some of posts in here, that they can connect to the Internet - through their PPC - when they are outside or walking or traveling from area to another, by scanning for the nearby Connection, then they can use it to visit websites, does this cost money when they connect to the Internet using the WiFi ? And how can I do the same if it doesn't cost m money ? Can the "WiFi Fofum" program do this o is it only to scan any available connection nearby ? How can I connect to the internet (through WiFi) when this programm finds connection? And if it is really totally free..
I know this are bunch o Questions But I really want to use this function - if possible - specially that I work outside my city and I have to spend couple of hours travelling almost everyday. I appreciate any comment.

Wireless router at home if you want to use it wirelessly or if you do what I do now and then..... connect via the USB cable to your PC. Out and about you can connect for free if someone has a wireless network within range that has no WEP security enabled
There are wireless spots around the country but you have to pay for the main ones via an account you have to set up (kind of pay as you go) Cloud is one company that runs WiFi hotspots on a PAYG basis.
If you leave your WIFI scanning it will tell you if you are within range of a network, it will also tell you if it is secured or not, if it isn't then 9/10 you can just connect and use it

I have been meaning to make a post just like the OP. You are on the mark, IMO! This situation really begs the question, how can this thing be so feeble out of the box?
Thank you XDA and all of the kind people on this forum. You have been the best!

In my case, my service provider (Cingular) offers a service called GPRS/EDGE, which lets the Wizard access the Internet through the cell phone connection.
I use the WiFi when I don't have a good connection. Most of the time, for browsing mini-websites and sending e-mails, there isn't much speed difference between WiFi and GPRS. I don't think the Wizard is fast enough to process more than a few 100 kbps of data.
If you don't want to (or can't) pay for a GPRS service, it's possible to "war drive" for access points. The Wizard will find them, although its WiFi reception isn't as powerful as a laptop's.
On my phone, if I enable WiFi, the phone will automatically use WiFi instead of GPRS when WiFi is available. If you don't want to pay GPRS charges, you might want to configure the phone so that it doesn't use GPRS.

can you explain 'wardriving' please? is it just freely using wifi points without paying? bit confused
Thanks

Jamie,
You are correct in your assumption !! You would be amazed at the number of 'unlocked' WiFi routers out there....
Ever tried running Bluetooth detection in a pub and seen how many phones are out there too ?
If you can find an unlocked WiFi router running DHCP - 'Fill your boots' !! Sometimes it's even possible to guess IP addresses of other PC's on the network, access em and leave a kindly note to thank them for their hospitality but warn them of their folly and the potential for disaster......I know I have but then that's me: Mr Altruism

Ok how can I get any internet connection through WiFi ? Should I just enable my WiFi and it'll scan for any available connection nearby ? I did but nothing happened, it wants from me to fill form which I really don't know anything about it... Or do I have to use a program to scan for connection ? And if yes, should my WiFi be enabled ? What is the best program for scaning ? I wish if someone explains me all that and how can start using WiFi to get a connection and an access to the internet but slowly, will be thankful.

Im new to all of this, but what can you do with the registry wizard and how do you install it? I foud a zip file for it, but cant get it to load.
Thanks!

i have a question too if you have the time mate,
I don't exactly want to use the edge since i dont have an unlimited plan or something.how can i delete these settings and do you think any problems will occur?(sending recieving mms)
basicly i don't it to connect to edge(gprs)auto.is there a way to fix this
thanks so much.

What do you think so far

I love my TyTn no problems at all, very fast and HSPDA rocks, so does the scroll wheel one handed operation is now a reality
Chris

So far, I'm very impressed with the speed.
The one-handed aspects (like the scroll wheel) are tremendous.
HSPDA definitely rocks. Depending on where/when I try, I've seen download speeds between 600kbs and 1.2mbs. Not too shabby!
I'm having issues with "Internet passthrough" access while connected to ActiveSync, but otherwise, problem-free!

OK.
Then please tell me the following:
(a) How do you conclude you are on HSDPA ? I assume you are deducing that from the downlink speed you experience, ain't ya ? Acc. to my experience you can conclude you are on HSDPA if you get good continuous rates of well beyond 400kbit/s.
(b) Then which software (PDA or PC-based) are you using for checking the downlink data rate ?
(c) Can you disclose in which town in the US you are residing ? Afaik Cingular has only recently rolled out HSDPA. So I'd assume you live either in or slightly outside a larger town to have access to HSDPA.
Something else - regarding the scroll wheel:
I agree, this could be a great helper for a one-hand operation.
Unfortunately I think it could work more intuitively and is in some aspects even lacking functionality where functiuonality would really be needed.
E.g. when surfing in the internet.
You can invoke the IE using the scroll wheel; but how the hell can you then access your IE Bookmarks ??? :-(
As a resolution HTC could have programmed the first up-scrolling movement with the wheel after invoking the IE as a trigger for starting the Bookmarks. What do you think ?
Also when scrolling thru the Bookmarks the wheel opens every sub-folder when moving on it, thus it needs really very long for selecting any specific bookmark if you have accumulated a big collection.
Why is the wheel opening a sub-folder when only a click at a folder should open it ? A little bit of a bug. What do you think ?
My opinion is:
The wheel definitely is a step forward, but still needs development.
Regarding HSDPA: There is no way of finding out if the device is really on HSDPA (same applies to EDGE btw) other than by judging on the downlink data rate experienced (which tool ?).
As my operator offers HSDPA here (and I get tremendous downlink rates using one of these Vodafone Mobile Connect Cards) I somewhat doubt that the TyTN already offers HSDPA capability as the speeds I experience (both when using as a surf machine as well as a modem) are good UMTS speed but really not HSDPA !
Which brings me back to my mantra:
"Guys, we need a generic way for distinguishing between HSDPA/UMTS and EDGE/GPRS, like the registry tweak for the predecessor models !!!"

Oh the TyTN does indeed do HSDPA. I live in a Cingular HSDPA launch city, namely Salt Lake City.
I've teathered it to my laptop and have acheived speeds of over 860/kbit download via dslreports.com. I can also acheive nice low latency between 200-300ms.
I have seen the device drop to GSM/EDGE mode when I'm in a bad area and the speed immediately drops to 100kbit or less.
At least in Salt Lake City, wherever the phone shows a U icon, I'm getting increadible speeds.
I ran the dslreports mobile test on the device and it gets the same speeds as when teathered to the laptop. Also I ran dslreports speed test through my wireless internet connection at home which is teathered to an 8mbit cable modem account. On this connection the TyTN tops out at being able to measure around 1500/kbit through pocket IE, so the average 600-800kbit over HSDPA must be pretty accurate. Very rarely am I seeing less than 600kbit download.
-James

For Salt Lake City let me clarify. When I have a U, it's always getting HSDPA speeds, when it shows a G, I'm always getting EDGE or less speeds.
Around here I assume everywhere we have UTMS, we have HSDPA enabled, this is how cingular did it. This is the same for GSM, wherever Cingular has GPRS, they have EDGE so whenever I see a G icon, I'm getting edge speeds.... now wether it truely is EDGE, or regular GPRS I don't care, in fact who cares, it's so slow compared to HSDPA the difference is not important to me. As long as I got the U, I know I'm getting HSDPA.
I guess for networks in Europe that deployed UMTS before HSDPA this doesn't help you determine if you are getting HSDPA or not. However from what I understand, if the network has HSDPA, and your phone is capable of it, then you just automatically get it. You are not selectively being denied HSDPA or anything, it's more spectrally effecient for the operator to let you use it if it's available. It would simply decrease their cell capacity to somehow deny you use of it.
A good example is on Cingular, I have a data package, I popped my 3G sim into my phone, and the same data login settings still work, only it's a hell of a lot faster.
Can you determine if HSDPA is indeed availabel on the towers in your area?
-James

In Europe, as the operators started off with UMTS a couple of years ago, HSDPA is definitely something of an "upgrade", thus not seamlessly switched on.
Would suppose its to a large extent a question of licensing and licenses have a better payoff where the services offered thru them are actually taken up by the customers.
This is surely the reason why there is generally not (yet) HSDPA available in every cell which is offering UMTS. (Agreed there are other reasons for that as well, but this one is a very important reason.)
As I live in the capital of my country and the HSDPA coverage is very good here (also other populated places in the country are well covered with HSDPA already) I can get high data rates using one of these high-speed PCMCIA data cards for the PC (e.g. the Vodafone Mobile Connect Card).
In the same cells I get a much lower data rate when surfing with the TyTN.
This made me wonder whether the TyTN at all already supports HSDPA.

My only complaint so far is the A2DP. The headsets I have tried with it do not have great connection. In that I mean that it connects fine, but there is always these constant pauses within a song (i.e., when I'm listening to a song) that drives me nuts. My M600 from Sony Ericsson does not do this as the connection is problem free. Also, the whole phone seems to slow down when I'm using the bluetooth headset to listen to music.
That's it so far.

There are some registry hacks that help the AD2P performance

jmacdonald801,
Thanks for the post. I'm in Salt Lake City too using heavily hacked Wizard on T-mobile's network. I love the wizard but have been missiing the Evdo speeds of Verizon but I need a world phone for my business.
Where'd you order your TyTN from and what is your cingular plan costing you?
Thanks again.

I created a big stink on ho-fo because my TyTN was defective and I tried to return it after the 7 day policy of the online reseller.
Listen, I would be neglectful if I didn't tell you you are taking a big risk by purchasing this device, regardless of where you buy it. As you may have read here, this device has a serious quality control issue. Even replacement units are not always bug free.
That being said here are some things you really need to consider when purchasing this phone.
HTC is not obligated to repair your phone outside of the countries where it is meant to be sold. The United States is not on this list. I read the warenty documentation carefully. This doesn't mean they won't repair it, it just means they can tell you to bug off at their leisure. You could end up shipping this thing back to Europe and who knows if you will ever see it again.
The phone will cost between $700 to $800. Now that's a lot given that HTC isn't obligated to fix it, and the retailers you will encounter online will only offer a 7 day "exchange" policy only. Not only that, this policy may not be made clear to you during the checkout procedure.
Now assuming the HTC didn't have the number of issues that have been reported here, I could recommend someone to buy it from, but I certainly don't want you to take the chance of ending up with a defunct device with no warranty and basically up **** creek without a paddle.
While the device is "fun" and "neat" I doubt it's really going to provide you with any more functionality than your current device.
Now onto some positive information...
I have an older $19.99 media net package. It has unlimited data. I get 1200 text messages and 200 MMS messages. This package will work fine on the TyTN regardless of what anyone at Cingular will tell you.
What they won't tell you is what the physical difference between MediaNet and the PDA/Laptop plan are.
Firstly, there is not speed difference, if you have HSDPA, then you get the speed, period.
Secondly, Media.Net uses a fake IP address, similar to what happens when you have a router at home. the PDA Plan will give you a real internet IP address that people can connect to from the internet. The operational difference is simple, Media.Net will not allow you to use Corporate VPN, I have tried. Skype, and about every other application will work fine on Media.Net.
I don't know why Cingular makes such a big Stink about this, I use Cingular video MobiTV and you can literally eat hundreds of megabytes of data using Cingular's very own Media.Net applications. It's really just a scam to get you to buy a more expensive plan, which is fine if you need VPN.
As for me, I'm in the process of returning my TyTN and I'll stick with the LG CU500. It's an excellent phone. I think I'll find a PDA with 640x480 and bluetooth and just get the internet via the phone over bluetooth. This way I only need to carry the bigger device around when I need it and the phone just works without any complication.
If you can accept all the complications and risks involved in buying an imported phone for that amount of money, then I can recommend a good person, however I didn't fair so well.
Wait for the Cingular version.
-James

James,
Thank you for the candid response. I was going to wait anyway. I get a new phone every 6 month now and I've only had the Wizard for 4. In browsing this forum, I see there's quite a few bug which need fixing. Your advice to wait a while is much appreciated.
My wizard is working so well that the only thing I miss is the 3G internet. T-Mobiles 2.5 G ain't bad for anything except streaming video.
You've made me very eager to try the device on the Cingular network.
Thanks again.

@rkorzuch
Thanks for the A2DP performance tip from the Wiki, works for me with ITech S35 - improved audio quality.

out of curiosity, do you ever see an "E" when connected to edge networks? or does the TyTn handle "G" as either gprs or edge and "U" for UMTS?
edit: nvm...read the FAQ. that kinda sucks...i hope someone can figure out how to enable the "E" icon for the hermes.

Hi
I live in Austria - I am on T-Mobile and I just gut 664kbit/s using http://performance.chello.at:81/
So that seems to be HSDPA

@mdajax:
No "E" for edge on the TyTN unfortunately. The known reghacks don't work. Some are playing with the bitmaps that make up this display but so far I haven't heard of any success stories.

just measured 1100Kbps, so much for my monthly data allowance at this rate it'll last approximately 300 seconds ......

HSDPA/3G automatic switching

Hello,
I have just upgraded to the official GPS ROM and I am on the Swedish 3 operator. I have noticed since the upgrade that the network connection is switching from 3G to HSDPA when there is a demand of bandwidth or simply when there is data in either direction.
I can see that the purpose of this was to make it possible and more reliable to place and receive calls during data sessions. I have figured out though, that with the old ROM, there was no such switching (but there was no distinction with the icon, so you really had no idea) and the connection speed was always constantly 1Mbits/s when using Internet Sharing for example. Now with the HSDPA/3G switching/throttling, the connection often drops down to 3G speeds and Skype-calls are lacking quality from this a bit when using Skype in the car which i do quite regularly nowadays using my Jabra JX-10 headset.
I also realize that there is still a problem with outgoing and incoming calls during these automaticly switched-on HSDPA-sessions. That is probably why HTC has decided to keep the HSDPA sessions as short as possible, that's fine, but what boggles me is the algorithm used for the switching. It seems to always kick in HSDPA in the beginning of a new data session, and after a short time of inactivity (while pondering what favourite page to open this time) the connection drops down to 3G and it won't kick back to HSDPA even when you start browsing again, until a certain period of "non-HSDPA-ratio" has been reached and the phone thinks it would be OK to kick in the highspeed again for a little while.
I also noticed that using Skype would keep HSDPA alive once you place a call from a fresh started data session and keep talking ;-)
This is not a particular problem to me, I was just wondering of anyone else here has noticed and had an idea of what the programmers had in mind?
BTW: I am running TomTom 6.010 and Franson GpsGate on the machine now and it works absolutely like a dream. I used to have a Blue-I Bluetooth GPS in the car (Trimble based chipset, only 8 channels but quite OK piece of hardware) but this is far superior when it comes to HOLDING a persistent fix also when moving indoors. The TTFF is quite fast as long as you are outdoors, most of the time i have a fix before i leave the parking space. I noticed there being a dynamic number of satellites of the receiver, sometimes i see 7 out of 8 satellites, and then sometimes i see 10 out of 12! Anyone noticed?
Thanks in advance! Cheers...

It’s not your phone that decide to change from HSDPA mode to normal R99 (384kbits) mode and vice versa. Everything are always controlled by the network. The behaviors that you describe are normal. Besides the HSDPA is quit new for the operators and new parameters needs to be tuned for best performance for every users.
BTW, the degradation that you notice. You are not alone that use HSDPA.... Its finally the big success for 3G

I use Phone Alarm profiles and BandSwitch to control my connection based on business hours. I get a poor singal unless on 3G where my office is located. I force it to GPRS otherwise to save battery.

I have similar problems, cannot receive or start calls when HSDPA connected. Shouldn't that be possible anyway, calling and transferring data at the same time? Or is this a network provider problem?

I too am on the Swedish operator 3. I have an unlocked, non-operator distributed HTC TyTN that I had updated the radio to 1.40xxx and the ROM to Black Dymond 3.5 and was having the exact same problem. I could reproduce the incoming call not getting through error every single time I got the phone to go into HSDPA mode.
After some initial searching I read somewhere it was network dependent (Nokia switches vs Ericsson) and the only way to solve it was to disable the HSDPA using e.g. HTweakC, which I did and it solved the problem, but then of course I couldn't take advantage of the high-speed data access, which was the major reason I got this phone.
I recently noticed that 3 released a new extended ROM with instructions to update the ROM to the latest (as is available on the ftp here) then install their ExtROM. I went to the trouble to try and breakdown what was in this extended ROM, but being a newbie to pocketpc it was all hyroglyphics to me, so I went ahead and installed it over my old HTC ext ROM (which I saved for later use just in case).
When I get around to it I may mount this extended ROM here (I have it, but don't have too much time to put it up right now, so someone may beat me to it).
Anyway, Black Dymond 3.5 didn't install the Extended ROM after a hard reset (assuming that was the intention), so I did it myself afterwards. One initial bug that showed up quickly was the Comm Manager not wanting to start saying it would only manage a max of 7 items (whatever that means). So I installed Schaps latest Comm Manager and it worked fine.
Well, guess what, now there's a daemond that starts on boot and the phone app is different (another bug is that the text on the phone app buttons remain in the 3 theme although I changed back to black, but that's minor), but now I cannot replicate the no incoming calls during HSDPA error.
Apparently they've added something that makes the phone connect properly to their 3G/HSDPA network for call handling. Now I've got full HSDPA speed and no problem on incoming calls (plus still have Black Dymond's great VOIP/SIP WM6 solution).

Ok, as a noob I of course missed the fact that the daemon starting at boot is Voice Commander. Still the actual phone app/dll is somehow different with this ExtROM and it's solved my problems.

Problems with Telstra HTC HD2

Got a HD2 on a plan with Telstra a few days ago. I see it has potential, but it has been a far from smooth experience.
I got rid of the locked icons on the home screen pronto as per the other thread here.
My remaining problems are as follows:
- I do not want to use the data connection for the internet. I assumed the HD2 was like the iPhone, in that when you turn off access to the internet via 3G, it is actually OFF. This little bastard connects to the internet when it deems necessary, often when I'm on a perfectly good WiFi connection. Is there any definitive method of disabling any other kind of connection to the internet except WiFi??
- I sync music from Songbird. I sync 5 albums, it's ok, I sync 5 more it's still fine. But when I get a good 50 or so albums on there, numerous problems ensue. Not all the albums and artists appear in my albums or artists list, only about 15 do. All the songs appear in the song list however, and it shows they're all correctly labelled so it's not a problem with the metadata, I'm meticulous with that. When I play a song, I get 15 seconds before Audio Manager or something to that effect crashes. In File Manager I can see all the artists/albums/songs nicely arranged in their folders, and they play in WMP fine, but who wants to use that?! What is the smoothest way to sync music?
I would consider flashing a new ROM if it would fix these issues. If I'm going to do that though, is there a copy of the original Telstra ROM anywhere I can reinstall in case of guarantee issues?

So you bought a phone with a 3G antenna because you don't want to use cellular data.
O...K...
Also: My phone uses WiFi when WiFi is turned on and cellular data otherwise. I don't know that it uses WiFi exclusively, but...

What's everyone's aversion to WMP?
I love WMP -- both desktop and mobile.
I hate the Sense music player, because you have no control over songs showing up there, it has an iTunes-like feel, and because it doesn't spawn a process that appears in the Task Manager that I can kill without going all the way back to the Music Sense tab.

He's talking about the Telstra Next-G release of the HD2. Telstra's HSPA network (they branded it Next-G) offers coverage to like 99% of the population or something in Australia, whereas their 2100MHz 3G and GSM/EDGE networks don't have nearly the same coverage. Also, Telstra only release non-3G phones on their pre-paid services now.
So, in conclusion, down here we live in a 3G utopia, and all we can just about get on Telstra are prettyful 3G phones.

I bought the HD2 because I'm often in WiFi hotspots, and TBQH I enjoy the break from the internets on the train and on the street.
When I am on WiFi, the data connection turns itself on, I assume to send data via that route. I haven't got my first bill yet so we'll see about that.

Cause it's butt ugly and completely out of keeping with the rest of HTC sense.
In any case, has anyone else experienced problems with loading large amounts of music on their HD2? Though I would hardly call 50 albums 'large' in the grand scheme of things.
