I know there are a lot of threads about this, but all of them seem to end with people wondering if there's any solution, or a conclusion to the problem. At this point it seems all this is clear as mud and therefore I'll try to give you all a final answer on how this goes down.
The Bell SGS2 i757M "HD LTE" or "Skyrocket HD" indeed can be used with AWS bands on 3G network. I have been trying for a while to get it to work on Wind Mobile. However it does not work 100%. Data and text messaging work perfectly. However the calls are very dodgy, and it gets better or worse depending on which radio you use. You can hear the person on the other end perfectly fine, however the person on the other end will get very bad quality sound coming from you. AFAIK there is no way around this. If you call people a lot best just to get a different phone.
Here is a conclusion of my trying of pretty much every AWS-enabling radio out there that people have said to try with the i757M. All of which were tested with CM9, however stock ICS would produce pretty much identical results. I tried some radios with stock JB and they didn't work, so for AWS compatibility stick with ICS.
Quality figures compared to what I would usually get with a native AWS compatible phone on Wind, in this case Xperia Ion
-T989D KJ3 (Galaxy S2X GB) - Doesn't work
-T989D TLLE4 (Galaxy S2X ICS) - Data speeds okay, text working, calls work, but takes ~10 secs to connect and start dialing. Bad quality, about ~40%
-T879 UVLG3 (T-Mobile Note 1) - Best data speeds, text working, calls work, connects instantly, but worse sound quality. Barely understandable on the other end.
-T989 ULVE1 (T-Mobile S2 ICS) - Good data speeds, text working, calls work, 3-5 secs connection, still awful sound about 30% quality
-T-mobile Blaze ICS (mod radio for i717 LTE Note1) - Pretty much same as ULVG3
-T769 UMVB1 (Blaze 4G) - Good data speeds, text working, calls work, ~10 secs connection but best quality out of all. Probably around 50% quality. This radio does not work with stock ROMs only CM
-T879 UMVA1 (T-Mobile Note 1) - Almost same results as UMVB1, but with a little bit worse sound quality. but This radio does not work with stock ROMs only CM
-T989 VK1 (T-Mobile S2) - About same as ULVE1
-I757M UGMC5 (Bell stock radio update) - Claims to be AWS compatible but doesn't work
Hope this helps somebody who's looking to use their i757 on AWS wind mobilicity or T-Mobile. If you want best data speeds go for the T879 UVLG3. For call quality use the UMVB1 but it still isn't quality that the person on the other end can live with.
AWS compatibility
I went through the same experience as you, however, I finally broke through the 75% AWS compatibility wall, when I learned how to set a fast dormancy rule for WIND mobile, to disable it. And the easiest way I found to do that, was to run an ICS rom. At that point, nearly any radio worked, but I always had an issue where, upon first boot, it would take five minutes for it to find the WIND network.
I am coming from the same place as you. The phone wouldn't see calls coming in. it wouldn't get texts till much later, if at all. The data would scream through, when it went(at 2am) but during the busy portions of the day, the radio would collapse, and turn itself off, after trying to many times and failing.
Once I set the dormancy rule(off) then it would sit and patiently wait for connection, it would keep the connection open when it finally found it, and so on.
ALSO, whereas the T989 can push 1-3mbps UP to wind, the i727, and i757, and i717, since they are LTE, with a different antenna, and different programming, seem to be limited to about 300kbps tops.
Hence, when you are getting a poor signal, and the phone is going crazy switching, then the uplink is the first to go. Hence why people can't hear you, but since these phones pull data faster, and the voice is transmitted via data, then you can hear them.
Disable fast dormancy. Use an ICS rom. Beyond that.........it can be a stable, fast and consistent phone and your speeds will be determined by the network congestion, instead of whether or not the modem is going haywire.

I asked SimonNWalker to include this in his table but I haven't seen it yet. I've tried a couple of dozen ROMs/versions over the last 6 months because I get seduced by the new features, but this to me is one of the biggest and I've had to revert back a number of times because many or most don't seem to support this.
I'm on the phone a lot using my BT headset and I love being able to surf while I am talking. Can any of the newer ROMs do this?
Are you using 3G or not? I'm trying to remember a time when I've surfed while talking, but I usually just talk when I'm on the phone. IIRC, I've been able to use the data connection during a call in 3G areas.
I am in a 3G area so much if not all of it has been on 3G I think. I know it is a full data connection because I can browse, send/receive emails, etc. while on the phone (vs. just SMS on many ROMs)
I don't believe its a limitation of the ROM.
From what I remember before I rooted my phone on regular RC33 I was able to talk and surf at the same time provided it was a 3G connection.
I think it might be due to the fact that you're dropping your data connection in-call. I've tried the following builds and they all work in regards to data use during a phone call:
JF 1.5
Haykuro 5.01-6.01
ION
Dude's 1.0-1.2b
Bottom line is this, while you're in a call, look at the status bar. If your 3G icon is gone or replaced by E, G, or nothing at all, then your phone is dropping data connection while in the call. Generally speaking, I have found this to be the case where my cell phone is bouncing a clear cell signal off of one tower, but the 3G signal strength is poor from another.
to use data and voice at the same time you have to have a strong 3g connection this is the purpose of 3g so this is not a rom problem its a poor 3g connection on your phone or no 3g connection where you are at
I've have never had a problem surfing and talking at the same time, on any ROM for that matter.
I will take your word for it but I have been using these forever I can definitively say that a number of the ROMs would not allow this while I am in my house while Haykuro's did. There are a number of posts from a couple of months ago as well where posters asked how it was done and at that time at least TheDude's versions and JF's wouldn't do it. The Haykuro 1.5's were relatively new, and maybe they can all do it now but they absolutely didn't do it in the past.
Good to hear, now if a good ION or Hero or Rogers ROM with Exchange comes out I will jump on it.
Just a simple poll to see how many people have worse 3G stability after the radio update. Personally, it's really bad for me.... I'll get about 5-10 mins of 3G (4 bars) access before it decides not to work in any app. To use data, I have to switch over to Edge which works 100% of the time.
I still get the same 3G as far as I have noticed, but I'm seeing some strange data rates: just tested at 903 down and 789 up. I've had more than a few of these results, even some where the up speed is higher than the down. All since the new radio. App I'm using is speedtest.net FWIW.
Hmmm... I did notice my 3G is faster but so much less stable. I still can't access the 3G since I started the topic. Hopefully someone else from Oklahoma sees this thread... maybe it's just my area.
I can get on EDGE all I want... I just can't do 3G, regardless of the fact I have 4 bars of it. It just pings the server every 5 secs and gets nothing in return, almost like the server is either refusing it or not there. I wonder if I have a bad APN?
I'm using the stock 2.1 rom+update from the other day... I installed a small superuser+highmem hack from modaco just to root it. No other mods/themes have been installed.
I believe the bars are just relating to standard voice connection status not the quality of your 3G. I could be wrong though. I think you can have a great voice conn and shoddy 3G and vice versa.
In Chicago and I have the same issue. I had no 3G problems before the update and now my phone constantly switches between 3G/Edge/no service.
My battery life is also very very poor now due to this.
Not very happy. Half the time I get no 3G at all now whereas before I had 4 bars almost everywhere.

Still having the problem... but after selecting T-Mobile, it now is showing the "upload" as solid instead of pinging every 5 secs... but I still get nothing downstream.
I play HomeRunBattle3D a lot and it constantly gets a weak connection or drops me out of the game.
At work I have 3G in only 1/2 the office now...
I flashed it to help but it def makes it worse for me.
I just applied the fix from above and will check back here after a few days...
I flashed this and I am using CM5 beta4 not sure if the E79 update has something else in the software as I dont think CM5 is using the OTA fixes yet so maybe the problem is there?
mine is difinately worse as well. Also after choosing tmobile network I think it made it even worse again. I assume this is similar to the problems others were having with the old radio when mine was fine. I was just hoping to maybe get some better reception with the new radio because that was lacking a bit.
now in my office where I used to get 3 bars 3g my phone is sitting here with 2-3 bars Edge. hmmm...I must admit though that it is browsing much faster on Edge than it was before...? Possible the roms are reading the radio incorrectly?
I used the phone on ATT edge before switching to tmobile and I was impressed by how fast even browsing was on ATT edge especially when Tmobile 3g didn't feel too much faster after I switched over. Tmobile edge was also dog slow. now Edge seems to have sped up a good bit....I might try flashing the stock rom for now and see how that does with the new radio.
Looks like those that are having issues are not running the stock rom (but have the new radio flashed). I'd be willing to bet switching back 100% stock (2.1 update-1)would resolve the issue.

I'm running stock.
Just to update everyone... I've had a good solid 3G connection for the past hour or so... with no hiccups.
*crosses fingers*
I'm beginning to think this is an issue on T-Mobile's end...
EDIT: Nevermind... there it went again.

I have not yet received the OTA update and I am seeing similarly large upload numbers today as well (it just started happening as of this morning). This is in the SF Bay Area. I'd be willing to be that they are more due to network upgrades than any changes in the 3G radio.
I'm on stock N1 bought on launch date. I had fine 3G before update and fine 3G after update. I would say I'm in 3G 99% of time. It even goes into HSDPA when I begin to surf and and when pages are done loading its back to UMTS..I've maybe only seen Edge once or twice since I've got my phone. I'm on Tmobile in Louisville .
It's been about the same pre/post update. It's rock solid 3-4 bars 3G w/HSPA most places, but bouncing between 3 bars of EDGE and 4 bars of 3G, with it usually being 2 bars of 3G at home. Before updating, it might have received one less bar everywhere.
3G seems to be around -100db, while 2G is around -70. Plus or minus 10db.
mine stayed the same, almost no 3G almost always edge, but now my GPS does not work.
Nexus on vodafone spain
I just had a single annoying problem related with 3G BEFORE the update...
And after the update...gues what?
It´s more of the SAME:
-Everytime I receive or make a CALL...my 3G connection switch to GPRS and doesn´t recover unless I change over Airplane Mode.
Please...tell me that I´m the only one
3G was fine before the update, and now rarely works, and takes a long time to start when it does.
Im in San Antonio TX and before update, my 3g would go to edge every now and again. Not too big of a deal really. But after my update (I did the OTA manually thanks to the forums! ) I get 3g constantly and have yet to see the edge pop up.
My connection is definitely much less stable. I now strugle to load pages when I have a 3g icon and at least 2 bars of signal. Before the update I had no trouble loading pages even with a really weak signal. Something is definitely ****ed with this half baked update.
I also posted athread on google support forums, please contribute your findings there as that i the only place where google can actually see feedback.
Here is the link to the thread:

Because this is F'ing ridiculous. I'm soon going to be on my 3rd HD2(T-Mobile is shipping me a new one tomorrow) the previous 2 just kept dropping my data connection. After about 3 hours of LESS of use my data would go out and only way to fix this is by doing a soft reset which is absolutely ridicules considering the damn thing just came out not less then 3 weeks ago. Am I just having bad luck or is there really an issue here that either T-Mobile or HTC need to address ASAP?!
UPDATE
ok now im starting to think it was T-Mobiles network not being able to handle all the new data over there lines or what not. Its been a full 2 days and I'm getting great data coverage. I'm getting my replacement HD2 tomorrow via UPS since I called T-Mobile and told them about the problem they said they would send me a new one. What should I do now. Its such a pain to have to set up my phone the way I like it but then again I dont want to risk having another data problem.

Dude, you are having some bad luck!
My phone is perfect. Well, it could use a keyboard, but otherwise...

I am have same problem..t-mobile 3g sucks i guess
It appears to be a common problems with HD2 users on the other side.

I was on the phone with T-mobile a few hours ago for an hour because my data connection would randomly drop. When I try to click it to turn it on, it would make me start a new data connection, wtf?
If I turn my phoen off and back on, it wouldn't even connect, with anything. The guy at T-mobile made me do a hard reset. My connection is fine now, but this was a hassle. I also notice Im not getting any better 3G service (as he said he update my network with better coverage).
I have the same problem with my phone. I have to constantly turn the data off and back on to get connection.
Both of my phones are doing it. They were both replaced recently too. Wish I could vote twice.
same here even if i have a full 3g bar data wont stay stable
No issues here.
been reading and stuff and more than half of the people with an HD2 have this BUT THERE IS A FIX search for it just like I DID

That's great for you if you have a problem lol...I didn't when I was on stock. Glad to be on Elegancia now...pretty good s***.
No issues here. Bayarea.
The other day, I was in the Dade County Fair in Miami and my cell phone completely lost all connection (not just data, but cell signal as well). It would randomly come up again for a few seconds before dropping. I soft/hard reset, took the battery out for a few minutes... nothing seemed to work, so I called TMO USA the day after to see if maybe I was in the middle of an outage, but nothing and the guy from tech support couldn't help either... I had better service with MetroPCS....
The data connection dropping happens the moment I set foot in my home. It switches out of 3G and the phone starts displaying Edge, which is a lie because there is no network connection at that time (try to update weather and it simply spits out a connection error). I'm gonna try to flash something else and see if that works (I am on stock right now). If I cannot get this solved by the end of this week. I am switching to Sprint and getting myself a TP2 (since I need SIM card capability in my phone).
I did notice one strange thing though. I used CleanRAM (level 3 option) at one point at home when I was with the faulty Edge, and it switched back to full 3G. So, at this point, I am starting to believe that TMO put something in the stock rom that either hinders, or makes the connection lousy...
I guess I put away my ORD for as long as I could with this phone
To put it lightly, T-Mobile plan sucks in my area, I had to switch to AT&T ever since then I havent lost any data connections.
Although I just moved to EnergyROM the other day since I just like that ROM since I used to use it on my Touch Pro. I never had data issues with the Stock ROM. Only time I had a data issue is when there was an outtage in my area and then even the phone didn't work.
I could not get my data connection to stay on more than a few minutes at a time until I loaded up HD2Tweaks. Since then, it's been running perfectly.
It's odd...however, if your phone's only problem is just switching between Edge and 3G try setting the phone to only run on 3G...under Settings->Wireless Controls->Phone->Baseband->WCDMA...
If your phone is cutting out...that sucks lol...not a whole lot I can think of except for the fact that the laws of physics apply in this case...the higher a frequency is, the farther it travels with less energy but the less it penetrates the environment around it. This is in part caused by higher frequency waves becoming extremely tiny, with over 1900mhz having waves that are smaller than a drop of water.
AT&T 3G uses 850mhz and 1900mhz for their 3G. Its lower frequencies don't travel as far, but they have more towers to make up for coverage area and the signal will penetrate.
T-Mobile 3G is 1700mhz/2100mhz meaning that the slightly higher range, while seemingly insignificant, when coupled with less towers, will cause the far end of the signal range to have too great a degradation of power, and not enough penetration to be viable.
Along with this is the fact that many government agencies still operate on the frequencies that T-Mobile purchased, due to not having a backup for their systems. Enough power generated within a frequency range will raise the noise floor enough that your phone's signal will get cut off. Sounds crazy, but it does happen quite often. You ever hear static on your radio? Analog is great in that you can lose data and still function. So government radio's are perfectly okay with a little bit of background noise.
However, signals that broadcast an analog translation of a 1's and 0's, function like a digital connection. When packets of information are lost in significant quantities, or in this case they are known are "frames", your phone cuts out.
Signal interference is becoming more and more of a problem in the cellular world. Satellite communications have had to deal with this problem for years. Only now are enough cell phones being packed into a single area for the noise floor to rise in significant quantities.
Just my $.02

for those who fix the problem can you post how you guys did it. i tried changing data to just 3g didn't work changing to voicestream it didnt work

Hi all,
I flashed my phone, and thought I’d go with Darky's Raw Steel Edition (4.1), which is awesome btw. I installed it correctly, installing I9000XWJM8 first (the MODEM and PDA, not CSC as none seemed to come in the package).
Everything was working smoothly until I realise 3G/Data Network is no longer working (it did previously). Not only that but it seems it won’t connect to my service provider (Three) at all (emergency calls only), and I’ve also now noticed GPS doesn’t seem to work at all, I can’t even get into GPS test mode. Wireless does however work though it being off, or on, has no impact.
I’ve tried:
Flashing different firmware - Stock JM8 and Doc Froyo’s latest JPO.
Hard Reset
Deleting and re-entering APN settings, though they were correct and already on the phone anyway.
Testing my SIM on another phone – signal is strong, inc. 3G on that.
I’m really at a loss here. Any ideas anyone?
Thanks
UPDATE: So, I won't bump this myself, but incase anyone finds this thread in the future: the gprs, gps, 3g, etc all work - just not in my house, on the SGS, anymore. I have no idea why - my other phone, it's fine.. and it used to be fine with this phone too. I'll update again if I figure it out.
the other phone works fine with the same sim you are using in the SGS?
Yep, the same SIM works in my old Nokia 6600 fold, people in my house also with Three are getting solid reception right now. 4-5 bars with 3g established.
It worked beautifully all the way home from work on the bus, just not in/around my house.
It's as if the local cell towers near my house have blocked my SGS specifically (can't receive calls or texts either). I did turn the wireless on and off in short succession (which would cause the gprs/3g to try to re-establish each time).. maybe I flooded them and they blocked my IMEI? Or is that just a ridiculous idea?
The real odd thing is GPS not working either (again, just around my house/street); surely it doesn't need a cell site for that?
It does seem as if I can't download apps from The Market anymore either, and have tried various cache clearing solutions to fix it (problem occurred roughly when I noticed my reception was nill).
You might have a problem with the band selection thing of your phone.. have you tried downloading/speed test when you /do/ get a connection? If it seems capped at 40kbps, you might have the same problem I experienced before, of being stuck on 2g. (Despite settings saying otherwise).
I fixed it by doing the solution to having a missing 850 band, the thread of which is found somewhere in this forum.
Thanks. That sort of worked earlier.
It made a slow data connection, and some texts came through.
I then went out to a location a few miles away, had a look and it was still on a slow connection type for a few mins, then all of a sudden it went to HSPDA (with the occasional 3G flicker) and was blistering fast.
Now that I'm back home, I've lost all reception again and can't make/take calls
[EDIT] Clicking around my phone in the hopes of finding something: checked product code in my nv_data.bin file with SGS Toolbox, and it's showing I9000HKDKOR; whilst the backup is showing I9000HKDH3G - could I be on to something? I backed up my efs folder after rooting before doing anything else - so, going to try restoring that.
I have a hunch based on a 2 year old post (http://forum.xda-developers.com/showthread.php?t=445913).
From what I understand, Three UK piggy back on Orange's network when Three's 3G cell towers are out of reach. Orange don't provide Three users with the full service though, just 2G and I'm guessing they prioritise Orange customer traffic.
I think when I flashed my phone, I removed code commanding the phone to prefer Three cell towers. Without that code, the phone simply goes to the strongest/first signal it detects. I'm guessing in the area near where I live, it's Orange (or maybe any old network which is why I'm often getting Emergency Calls only).
This is all guesswork. I'm hopeful, seeing as if I quickly switch the SIM to my two+ year old phone, then I quickly get 5 bars and 3G.. unless the SGS's signal issues really are *that* bad.
http://forum.xda-developers.com/showthread.php?t=831022
Try see if you have the symptom of a missing band?
Hi Nwsk, I tried that before and assumed it didn't work, but actually the change isn't sticking. Which seems to be the case for a couple of others! Thanks for pointing me back to it!
[Edit]
Ohhhh dear. Now I have another theory (I really hope I'm wrong).
I've just read on a thread that some phones don't have the 850 Band, it's down to a lack of hardware support. I'd wager every Three UK branded phone sold will have the correct hardware as stock. I sent my phone back to Samsung for repair, they said they replaced the motherboard.. inference: they replaced it with one without the WCDMA 850 support.
Hmm, I'm definitely no authority on this, since I'm just guessing.. but I figure if that if was a true hardware defect, you wouldn't even be able to get it temporarily?
Are you using any 'battery-saving' type apps? Something might be messing up and keep reverting the settings. I had this occur to me a second time when I was trying out the superpower app here, I think it conflicted with another app I was using, and it borked out my network connectivity. Somehow fixed that after a few reboots, and lots of messing around in the phone debug menu with the 3g/2g thing, it suddenly worked again.
I've not seen it manage to get onto 850MHz WCDMA in my house for a while, not since the mobo got replaced (I should qualify that with a statement on my bad memory ). It will occasionally latch onto something if I walk around the house, giving me a slow data connection with the G symbol showing - it will drop pretty quickly.
Messing around while I write this, I've just realised if I set my phone to GSM(2G) with roaming [Three UK phones need this on so they can connect to Orange towers], then it does establish a data connection at 1800mhz. If I force WCDMA only, I get NOTHING. Setting both/auto leads to it being dodgy/instable, as I've discribed above.
My Nokia 6600 supports 850mhz UMTS, which would explain why it's working well inside my house.
I don't think it's an app. I've flashed a few different firmwares in an effort to get this fixed, it's currently on official Froyo JPO (not even rooted!) with Multi-CSC and a few completely harmless apps. I'd try the stock Three firmware if it was available somewhere.
I'm hoping it's software like you suggest! I will tinker away for now!
Thanks for all the help, at least now I'm fairly sure I'm on the right track!
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.

Right, a little back story.
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.

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?
