AT&T 850 MHz and Location Services - HD2 General

I have a problem. I must have tried 10 different ROM's in the last few days and I am getting extremely frustrated.
I have an HD2 (Telstra Version) that works on the 850MHz band for HSDPA.
Everytime I am on HSDPA, the location services stop working... Weather panel, Bing, Google Maps, nothing can find my location based on cell id... GPS works fine...
When i switch the 3G off... location services work perfectly fine.
I have tried different ROM, Radio combinations, but nothing seems to work...
I have tried NRG ROM, Dutty's HG (preferred) and ML series, but to no avail.
Can anyone help me troubleshoot this problem further, or has anyone else encountered this... I would really like some help on this.
Thanks a lot.. beers/coffee on me...

It works!!!
Bless this forum and bless the users on it!!!
Finally i think I have a fix...
Hi guys. This seems to be a nice friendly informative thread. I too WAS having the data disconnect on my phone.
I have the 1.66 sea wwe official rom. I tried every radio from the telstra radio to the new 2.08.50.08_2 radio. To tell you the truth I didnt notice anything different between any of the radios. So I really can't say if one is better than the other. But I started changing settings.
If you are in a 3G (H) 850 area I suggest this.
settings/Wireless controls/phone/band
for Network Type choose WCDMA
for Band Frequency choose the third setting. On Telstra rom it will be GSM(1900)+UMTS(850) and on any other rom it will be GSM(1900+850) and select done.
Now this should stop most of that switching you see in the taskbar of your phone. But this isnt actually what is causing the freezing. It has to do with your sms messaging I believe. I went 2 weeks resetting my phone twice a day. Then I went here.
settings/menu/all settings/connections/advanced network/sms service
Right now GSM is working for me. 4 days and no internet freezing. I believe your incoming email might be coming in by sms also. Notice you only get a few lines and have to download the rest using data to see the whole email.
Others on the forum have turned off email and their phones quit freezing. So if GSM doesnt work for you try GPRS and so on. This is only my opinion but I have been very happy for the last 4 days. Thanks for letting me share this info.
If anyone is interested I have made a cab file which is un-installable that will change the Band Frequency menu to the menu from the Telstra rom. It is mostly cosmetic but at least you will know what bands you are selecting. Use at your own risk of course. I have installed, tested, and uninstalled it myself. No issues.
For the last 4 days with these settings I only see 3G while phone is setting idle. As soon as I connect to the internet it switches to H. I am very happy with my phone now. Thanks matthewf01 for starting this thread. I should have came here sooner.

Signal problems i didnt have with my Wizard

I got the Hermes (cingular 8515) a couple of days ago. And everything is just fine but the most important part. I keep having dropped calls in places where the Wizard didnt have any problem at all.
ROM: 2.06.502.3
RADIO: 1.34.00.10
PROTOCOL. 32.67.7020.10H
I had the shipped ROM but i had this signal problems so i upgraded to this one in the hope that the problems would be solved but same thing.
Cingular did change my SIM card to a 3G one. I was wondering if it is a different network inside cingular and that is why i have problems. I really dont care about 3G, don't use it. Would my problem solve if i ask for a new regular SIM?
Thanks guys. I looked a lot for the same problem already posted so i dont repeat but didnt find anything, wich worries me a little
Yes, it could be that, because if you're in a major metropolitan area it'll try to use UMTS instead of GSM.
In any case, there is a fix:
http://forum.xda-developers.com/showthread.php?t=286844
This is a small app that will allow you to quickly change back and forth between the two.
If you don't want that, there's a reghack to enable a Band page in phone settings where you could force it back to GSM. Check the wiki.
Wow! thanks! it looks like the problem was solved!
I won't know for sure until i really tested it. But this is what i wanted to try

Mobile Reception Inconsistant after hard flash!!!

After doing a Hard Flash for the first time from 1.43 to 148 and rebooting my HD2. Within several minutes my reception speed would change from 3G to GPRS and back again while on the go, this has never happen before and was wondering is there a way to have consistent 3G speed/reception or was there a fault during my flash?
Any suggestions or help would most helpful.

Did you flash with SSPL / Gold card or with the HDSPL in-tacked?
EITHER WAY:
Press Phone Key>Options>GSM/UMTS Services:
Here select Band....then, "Get Settings"
The first tab should say GSM. Drop down menu option you want is WCDMA. This will force 3G all the time. However I don't recommend this setting as this will consume more battery.
Leaving it in 2G saves more battery and voice quality doesn't change....
hi,
maybe you flashed the radio part of the rom also, when you flash from 1.43 to 1.48?. im not sure, but you should check out this htc update, and try it. its a replacement for the radio portion of your rom only, and maybe fixing your problems. my singnal strengh has stoped to swing between full and no bars, and i have full bars most of the time, with this update.
regards mad.

Stock Roms include the Radio so if there was a change between one stock and the other then a change will occur...
There is nothing wrong with the radio band switching automatically though so unless you have bad reception, everything should be fine.

HSDPA, will donate for help!!

Hi guys, i know this is a common problem amongst some of us, there are several threads discussing the connection drops but please there must be someone out there who knows something about it.
Basically with HSDPA enabled, the connection will last a random period of time before disconnecting by itself and displaying: cannot connect for an unknown reason.
When HSDPA is turned off, only 3G is used, although this works fine, it is fairly slower.
I am on T-Mobile UK, I have phoned their technical support, we have established it is not the sim card but the phone itself and have tried a variety of steps to solve this, for example receiving band settings for WCDMA, this has not fixed the problem.
I have tried changing the username and password combinations and have tried every combination of every advanced network option. I have used the T-Mobile stock rom 1.43, official HTC ROM 1.66, duttys hg, energyROM, artemis 5.0 and artemis 5.5 (would recommend btw) using MTTY before every flash, and every single different radio combination.
Myself, and many people here would be very grateful for any help posted.
Thanks in advance
Why don't you try Settings > Connections > Advanced network > GPRS tab > change from PAP to CHAP.. and reset... or viceversa.. that helped for me..
Thanks for the post, i've tried all that i've tried all advanced settings, at most they last for a day or so but after a while the connection dropouts seem to worsen
Ok ive just gotten off the phone for the third time with the technical support
basically what they've said is that the hsdpa WILL disconnect because the mobile towers simply can't handle the traffic.
He said in his honest opinion I should disable it because it simply won't work well and there is no fix.
Taking the piss juuuuust a little bit
Mine on t-mobile uk will show H, but usually drop down to 3G. It won't give me an error when it drops down though.
It sounds like its not transferring from H to 3G.
To be honest, i was unaware t-mobile ran HSDPA till I got my HD2 (never showed on my BB).
mine switches between 3G and H too, this happens when the connection is being used (for example loading a web page) when the job is finished (page has finished loading) it turns back to 3G right?
are you saying that your connection never disconnects?
may i ask which radio and rom you are using?
thanks!
For my personal experience, I have for over a month, on versions 1.48, 1.66 by HTC, artemis versions, versions of other French chefs. had no problems,
Login Exchange push 24/24 without any cuts, I solicited the network with opera I passed automatically 3g H, and since February it to completely fall with the problems that everyone encounters (lost connection for several minutes , unable to connect to 3G without hard reset)
to remove the sim chip, I try with another chip of the same operator, another chip from another operator, the problem is still there.
For several days I have also continued a Touch HD, it faces no problems, no problems in connection 24/24.
In short, impossible to challenge any operator, any base station, any sim card.
It is then that the problem come from HD2:
-Software: We all try every combination of rom and radio rom possible.
It is the hardware, maybe the chip integrated into a concern for design, manufacturing concerns on some series, may be dysfunctional due to incompatibilitée between several chips of the phone, short, HTC should look into the problem.

correct, it never disconnects.
It will switch seemlessly between them, when using or not using.
same one it came with. O2 HD2.
ROM 1.43.206.4 (70315) WWE
RADIO 2.04.50.22_2
I've also been struggling with this problem ever since I got my HD2 three weeks ago. However it seems like only a few people experience this.
My case is exactly like cgrec92 described. I'm on a 3.5G network in Denmark (3 Mobile), the phone shows the 3G connection at all times. When things do work and I use Opera/weather/Twitter/email etc, the symbol changes to H and I know the data connection is functioning. I can be using this for a whole hour without any problems.
However, if I put the phone down for a while and then pick it up again to use one of its data services, very often it does not connect to 3.5G (or H) anymore. It will still show the 3G icon on the screen, but there's no data connection. Then I go to Connection Manager and I can see that data connection shows as Off - and after a few seconds it goes back to On by itself That does not mean the problem is solved, as the phone still fails to establish any data connection. What I need to do then is manually turn off data connection and re-enable it again, which makes the 3G symbol immediately change to H. Then everything starts working again - until the next time it stops working...
I contacted the HTC customer service and they said it might be a driver-related issue, recommended a hard reset. I did that and for a few hours I thought it solved the problem, but no, data connection still disconnects by itself.
I spoke to 3 Mobile's technical service and they told me to update my software, which I had already done previously (I'm running stock 1.66 ROM Danish). They also said they never received any such complains about the HD2.
Like cgrec92 I've also played with all kinds of network/band settings, but it did not make any difference.
***
One question: isn't the phone supposed to automatically connect via EDGE when it cannot connect via HSDPA? Because in my case it will only establish data connection via H, never EDGE.
Any advice is greatly appreciated!
My take on this FWIW
It's not the phone!
It's the radio ROM installed.
I live in an an area where T-mobile say I can't get HSDPA.
However, I know that I can. How? Because 3 network uses the same local cell and transmitter as T-mobile and their signal will rip your eyes out!!!!!!!!!
All information obtained from a good friend of mine who works for BT, who, service manage the cells for the networks.
Plus, in this location, the cell traffic is then handled by BTs digiatal backbone which takes it who knows where after that.
So I have a very isolated situation in which I know there is a decent HSDPA signal, but I have had trouble with drop outs on my two previous phones (Nokis 5800 and HTC Touch Diamond 2) and originally on my two T-mobile mobile broadband feeds using Huawei E220 cell network modems.
All fixed when I finally found the right Radio and flashed it on the phones and unlocked and flashed the latest modem firmware.
My broadband connections are always on and never drop out and my HSDPA signal on my HD2 is through the roof!
To further emphasise the point all the equipment is used (when home based) behind solar glass which is notorious for blocking mobile phone signals.
Land on the best one and you will get incresed battery life as well.
Bottom line is try the latest radios (2.08.50.08_02 in my case) and I think you may be surprised at the results.

I have the same problem with the connection dropping. What I did to make it work was to disable HDSPA and putting GPRS to CHAP instead of PAP, and so far I have no problems at all
Thanks for the reply and tips. I also did the same earlier today, except that I did not change PAP to CHAP :O. I was waiting until tomorrow before I posted any results, but I gotta say so far the connection has been stable just like yours.
I also called HTC's customer service in Denmark and the fellow I spoke to was very helpful but he said he has never heard about such problems. He sent me updated network settings via sms, but it did not fix the problem.
I mean, only some users around the world suffer from this problem, right? So what is it that's wrong with our devices? Is it a production fault? If I exchange my phone for a brand new one maybe I won't be unlucky again? When 3 DK finally told you the problem was unfixable, did they mention other users with the same issue? Did they ever offer to replace your phone?

Erm!
It's your radio!
But, I think I did say that in a previous post.
You had a helpful fellow who sent you updated settings?
And he thought that was going to fix your problem?
That was helpful!
It's your radio!
The technicalities are beyond a customer assistant at the end of a phone. They work from a script.
I'll send you the settings.
Have you done this?
Have you done that ?
Never heard of anyone else with your problem!
It's your radio!
T-mobile uses PAP protocol (at least they do here in the UK) and it's a handshake protocol so changing that won't really do anything to the signal definition.
You have it or you don't.
It's your radio!
There is no "production fault".
You are not "lucky" or "unlucky".
You are in an area where you will suffer from this because of the ???????
THE RADIO!
I think I have made my point.
If it turns out that you don't have a radio issue then please feel free to admonish me.
Until then----------
It's your radio!
well I don't mean to sound rude but do you SERIOUSLY think we haven't tried that? ive tried every possible radio available here and every different rom, so excuse us for trying new things.im glad your not having any troubles yourself because it is really annoying
perhaps you could post us your rom and radio?
I don't suppose you could post us your settings in advanced network?
did you use the connection setup?
thanks for your help
Yes, I was about to mention something similar. I haven't tried combining different ROMS & Radios myself, but I know people like cgrec92 who have with no good results.
And if it is the radio, then every 3 Denmark user like me would be experiencing the same problem, correct? I don't think that's the case. Actually when you read the forums you will find users from different countries with this problem, and they/we are not the only ones with a certain combination of ROM/Radio.
So yes, by disabling HDSPA I finally managed to have a stable data connection (but no 3.5G, obviously). At this point no one seems to know the cause of this issue, but I suppose it's naive to expect a future ROM to solve it, after all it's not a widespread problem. Is HTC even working on it? Are we sure it's not our devices that are faulty?
I honestly have no idea, but I cannot just accept this problem and live with it after all the money I put into this phone. That's why I brought up the possibility of having it exchanged for a brand new one in hopes that it will not have this problem.
Any ideas?

I referred to my radio in my previous post -20.08.50.08_02.
My OS ROM is Leo Lite 3.
Connection setup used and no further settings.
My explanation for this is the fringe nature of the received signal.
The radio its constantly 'hunting' for a signal and the radio software has difficulty in locking on.
BTW OS ROM and settings ready don't affect the efficiency of the radio signal.

I appreciate the help, but he doesn't seem to understand the issue here. It's not that we have low connection, or that we cannot connect to the 3.5G network. The problem is that the phone's data connection will automatically disconnect even when we are in an area with full 3.5G signal. The phone will connect for a while and then, moments later, in the same spot and with full signal, data connection is terminated. So I just can't see how the radio has anything to do with that, especially when there are hundreds of other users out there with the same ROM & Radio as us and in the same network. And yet they do not experience this problem.
Ive have similar issues but it depends where i am it appears that some towers its ok where others its not!

The radio differentiates between all the different levels and types of signal and it depends on how exact it interprets the signal. They are supposedly optimized before release and then re optimized with each newly released version. Network operators then have their own network parameters and again the radio has to accommodate this as well. One radio will never satisfy all these criteria and some of you will be in the wrong place at the wrong time on the wrong network with the least effective radio.
I can assure you that I most certainly do understand the problem and that is why, in my own case, I have resolved it.

3G not working, but HSDPA is.

Hi All,
For 2 weeks or so now I've been having an issue with my Hero's internet connection. Didn't notice specifically when it started as it only affects the 3G connection and I mostly get HSDPA in my area. I use WiFi at home anyway.
When the notification bar shows 3G, the upstream arrow flashes periodically but there is no traffic downstream. Market downloads fail, anything which requires an internet connection will timeout.
However as soon as it switches up to H connection, it starts downloading immediately. If I switch to 2G only GPRS and EDGE connections work fine too.
Around the time the issue started I was trying a few different 2.1 roms for the first time. Have flashed several different roms since and have the same issue. Currently using VillainRom5.5. I was already using Radio 63.18.55.06JU_6.35.09.26 but have reflashed this too. Have flashed the stock Orange RUU, RUU_Herrange_UK_2.73.61.5_release_signed_NoDriv er.exe, but the issue remains.
Didn't have a problem, especially at home, before trying the 2.1 roms. I have good signal regardless which connection I have, currently 3 bars.
Thought it might just be an issue around my house but have tested all over and it's the same. Became an issue this week as I was visiting Somerset and in area's without HSDPA. Had to switch to 2G only in order to get internet connection.
Have searched here and other forums but cannot find anything specifically like this, any help greatly appreciated!
Cheers,
hello,
I had a lot of problems with connections (3G/HSDPA/2G) with loose of signal.
I tried a lot of ROMS to solve this problem. But It wasn't the right way...
In fact, My SIMcard was defective. I had to change it, and now all is OK.
I'm not sure that it will be the right issue for you, but perhaps It could be...

Cheers for your reply.
Have contacted Orange today, the customer services guy tried some stuff and asked me to test and call back. Hasn't helped so will call them back in a mo and report back.
Hi,
I am having a very similar issue and I am also on Orange. My issue started after around the time I flashed Villian 5.3 but I doubt this is the issue as I have flashed other ROMS since and have the problem. Have you also done the 2.1 battery stuff by *#*#4636#*#*? I did this around the same time the issue started and I thought it was because I had set it to GSM (auto) but I put it back to WCDMA but that made no difference.
My phone keeps showing 3G then swapping to HSDPA. This is both an my house and in the city. I always got H no matter where I was but now keeps swapping after a couple of mins or when I use internet. I've reflashed ROM, radios and tried a friends Orange SIM and I get the same.
I also have the exact same problem on the 3 network in the uk, definately not a sim problem as before I rooted and flashed it all worked perfectly. Hasnt been too much of an issue as most of my city has hspda coverage but if I go out of town its a pain.
Problem started as soon as I flashed a villain ROM and is present in all 2.1 ROMs I have tried although I have noticed that the legend ports seem more stable and connect a little better, so am currently running the villain 4 ROM. Updating the radio made no difference and I am starting to wonder if it is some thing to do with using a CDMA port?

Yeah I did try that stuff, I too have set it back to WCDMA Preferred. Now you mention it I guess my issue did start around this time too so its likely to be linked.
It does seem too coincidental that we have done the same things and are having the same issues on Orange. I'm going to wait to see if ROM from the official 2.1 build sorts it out and if not swap the phone out. I've had Villian and now BeHero + and still have the issue. I've flashed different Radio's as well and that has not fixed it.

Ive had this problem for well over a month now, way before the gsm auto trick came on the forums and I started using it, I dont think thats the cause, dont think its a radio issue either as had it on two diff radio versions.
My issue started as soon as I flashed a eris port which as far as I know is cdma based and isnt that a different kind of network than we use over here??
Any devs want to chip in here and help some noobs plz?
I've always had this issue with Orange as well, regardless of ROM, prior or after to flashing. I thought it was just the Orange network capacity as when I use the phone out of peak hours (2-7am) its fine.
I have the stock Hero with 1.5, no roots or custom os & it happens to me on Orange UK.
No idea why, but don't think its to do with custom roms!

Yaeh i have the exact same issue, tried many different roms, including official orange roms. This issue started before i started playing with customer roms.
Anyone have any suggestions?
Just adding to the list. Same issue for me, Orange UK - not specific to any ROM (Stock or Custom)
I'm going to join the party and say I have this problem too.
Although I didn't notice until I read this and checked, I just assumed Oranges 3G network was unstable in peak times

I too am on orange uk and tried this and experienced the same issue.
The solution is just reflash rom and radio (no wipe etc so data remains). That fixed it for me.
Also don't mess with *#*#...... settings
I'm still having this issue, maybe it is just the Orange network thats to blame? Seems to be to a number of us cropping up.
Gonna get back onto Customer Services this weekend, see what they say this time.
Same problem here. I'm on Orange UK too. Seems like an Orange network problem rather than a ROM problem
Saw this on my G2 Touch Hero on t-mobile when using villainrom 5.2. Not seen it recently and don't think its related to flashing 6.0.

Thought I'd update this.
Been living with the issue since posting, tried a few roms, all with the same issue.
Tried the latest radio, that didn't help.
Flashed EzHero rom few days ago and 3G has been working fine since! Don't know whats in this rom which might do that, it doesn't display the 'H' icon anymore which is the only visual difference. Might just be coincidence but either way glad its working consistently again.
I've had the same issue here on the other side of the pond in Canada on the Telus Hero. I think it has something to do with the phone trying to default to the fastest connection. I'm assuming the providers don't want us connected to the faster networks constantly, so they have a disconnect on idle response; which in turn is being counter-acted by our hero's need for speed. That is one theory, but I have to include that when I first got my TELUS Hero, before rooting and installing MaDaCo 1.5 I would have stable 3G connections. Any ROM installed following the root of my phone has caused this same dilemma.
This is a big issue on orange one which I have never got to the bottom of.
Now my phone seems to work 99% of the time but it always switches to H before downloading.
It might be something to do with Orange switching to new "next generation" towers. Apparently last time I phoned orange my phone was connected to two towers (only supposed to be one) so it was impossible to triangulate my exact position.
This might have something to do with it.

Possible fix for data stalling issues some of us are having.

Right, a little back story.
I brought my SGS2 at the start of May in the UK on O2 so I have an early model which came with the firmware before KE1. I rooted in the first week and was flashing Villainrom 1.0 before too long with no data problems.
I think it was around KE2 with Lite'ning rom that I first saw my phone constantly switching between H & 3G and stalling when receiving or sending data. This behaviour has continued through all the firmwares I've tried with many different modems. I moved onto to Cognition when it was v1.01 and have been using it all the way unto 1.2 with the KG3 modem. Again still with data connecting problems.
Things I have tried -
Turning off fast dormacy
Editing the build.prop http://forum.xda-developers.com/showthread.php?t=1097612&highlight=build.prop pages 1-5
Switching off HSDPA/HSUPA via the *#301279# command
Disabling juice defender
Switching to WCDMA only
Changing modems
Full hard reset and reflasing of roms
Even with the above on multiple roms and rom versions my data connection was unreliable at best and killing spree warranting at its worst.
Possible fix-
What i found lurking on XDA on a slow day at work was the command below
*#2263#
This allows you to select which bands your phone uses. I selected option 2 then tested the 4 available bands. They all resulted in a complete loss of reception except WCDMA 2100. this is probably network specific you'll need to try it yourselves.
The results and current settings
Now when I try to use my data connection the phone no longer switches between H & 3G. It will start on 3G then find H and stay there, I see a slight delay if its been in deep sleep or JD has cut the connect but this is normal for the phone to start on 3G to save power.
Fast dormacy - off
build.prop -stock/unedited (I found this worked for me for a while but since 2.3.4 it didnt seem to help)
HSDPA/HSUPA via the *#301279# command - both on
Juice defender - on
WCDMA only selected as when picking a band it doesn't seem to like having a GSM band selected as well (happy to be corrected on that)
Modem KG3 -
Rom cog 1.2 - I'm patiently waiting 1.4 based on KG6 to test my findings.
Conclusion-
Okay it could be that selecting a band does F'all and that I'm seeing better results for a completely different reason. I'm not a developer so my fixing skills amount to playing with stuff I don't fully understand and seeing how more or less broke I've made it.
After thought -
Ive seen on the sensation forum they have discussed the wrong IMEI code being the cause of poor data speeds so I may look into that next.
Please share your experiences and anything else you've tried.

That should be no connection as IMEI belongs to phone and handshakes with network first .
KG6 modem some report as better .

I will have to give this a try and see how it works, thanks for the share.
I am in the same boat, it is VERY frustrating to say the least. A typical scenario for me is: reading a web page on my S2 for a good few minutes (3g has gone to sleep mode by the time I have finished reading), I click on a link, 3g flashes, H comes up and flashes once.....wait.....wait.......wait......10 seconds later it decides to initiate a connection and take me where I want to go! It does the same thing with the XDA app. I have been onto O2 about this a couple of weeks ago, all they did was give me the settings over the phone (which were the exact same ones I already had) and they also sent me a replacement sim card, suffice to say, there is no change. Now I am convinced its a network problem of some sort, I have a three sim card which I have been trying out and the above problems do not exist anymore when using three, I click a link after 3g has gone to sleep and it goes from 3g to H and initialises the data transfer in one smooth motion. It looks like I'll be getting my PAC code and moving to Three!
would be interested to hear if switching to the 2100 band helps at all seeing as your on O2 as well
Mine is O2 via Giffgaff and no problems at all .
Tested KG6 modem Wi|Fi only and it is a stronger signal .

Yeah, forgot to mention that, I have just enabled it. I can't test at the moment though coz there is no 3G coverage where I am. The only problem with enabling it is you will not be able to connect to GPRS or Edge if you need to. But it is worth testing regardless.
Just been out and about and tried that setting, didn't make much difference unfortunately
Maybe it was a combination of tweaks on my end. What rom & modem are you using?

Villain 2.3 with KG3 modem. The problem has been the same whatever ROM I have used, I even flashed back to O2 stock a couple of weeks ago to see if it was a ROM problem, but that was the same. I can't remember what it was like when I first got the handset though, mine was the first batch as well.

The wife is on Giffgaff so I think I'll give that sim a try before I get my PAC off O2.

hi
i am just testing now this fix. i have an o2 phone and i did the same changes you did, disable fast dormancy, changed build.prop settings, will let you know after going a few times underground ;-)
gabrio
confirm, this is working, even when i go underground or when the signal goes away, it gets back to H/H+ and works, gabrio
Give it a little while, I think you'll be back saying it didn't work
Personally, I went ahead with my threat and moved over to 3uk, never looked back since with this problem, been perfect!
I've tried it all. Disabled fast dormancy, hspa, toyed with band selection, edited build.prop (btw, don't bother with it, the network settings you find on the web to type in don't work on the s2) you name it - but it would still cut out. Luckily, my phone is unlocked so I switched my provider and now it works like a charm with all the bells and whistles enabled. I can ride the tram all across warsaw and maybe have a handful of 2-3 second hiccups when I'm listening to online radio. Curiously enough, on my previous provider I've noted that there are some areas (like a busy mall - Arkadia) where it would not stall as well as a few other places, and most other areas that were notorious with data hanging. I'm convinced now that it is an issue on the telco side (*cough*Orange*cough*), and too bad because I was on a prepaid plan with them that for roughly $30 I had 7GB of transfer. I guess they figured they can promise the world on their trash network, because nobody would actually use it up. YMMV.
Had this issue with a UK GS2 purchased from Negri using it on AT&T.
Since upgrading to the latest UK firmware with 2.3.4 I have not had the issue going on about 2 weeks now!
Man was that issue annoying. Had to restart the phone sometimes to get data back.

Ok I did that too though how abt lag? Phone lags a bit opening large sms conversations and browsing home screens.. But peace. Yours too?
