I've had the US version for a few days now and figured I would share my experience thus far. This is not a definitive list. I ordered through sonystyle.com and am operating on T-mobile in the US.
The good:
1. Phone build is spectacular.
2. Screen resolution is the best I've ever seen.
3. Wifi picks up and logs on quicker than any phone I've had.
4. Touch-flo cabs can be added very easily. Can mix and match the two GUI's.
The bad:
1. Internet and regular calling access is sporadic. I need to perform a soft reset every few hours or nothing works.
2. A fully charged battery will be used up by evening if push email is auto and have moderate phone use.
3. The phone doesn't seem to be able to switch towers in the middle of a phone call. The calls are dropped and you have to call the person back.
Overall, the phone is really incredible and it's being hampered by OS build or something. If the phone didn't have the potential that it does, I would send it back. I figure I'll be patient and wait for the dev team to patch or cook something. I've used the HTC Touch Pro (Fuze) and the Xperia is definitely more sexy and has a better build and keyboard (personal opinion). It will be interesting to see if any others have the same issues and if it's associated with T-mobile US only.
cooool you have the X1a? Do you mind dumping your ROMs please?

none present on my X1i. For the battery, just wait, is still new... use it for 5/6 cycles and should be better. Also no issue for internet/calling and don't understand what you mean about towers...

1°) The BT and wifi are bugged. The BT disconnects sometimes (already told in other threads) and the wifi passwords are sometimes just lost.
But on 3G/GPRS/UMTS no problem and no need to perform soft reset.
2°) ouah, perhaps you have a problem there... I have (in France) a software that retrieves the mails (every 15 minutes) with a specific data connection.
This with some Wifi on, UMTS on and some calls, my X1i makes a lot more than a single day.
Did you install something that is draining the battery?
3°) weird, I live in a place where 3G signal is low, and I definitly swap from "2G" to "3G" without a hitch, even while a phone call.

I have not had any problem with #1 and #2, and I'm also on pushmail mode. By the evening, I would still have 50-60% depending on the activities I carry out with my Xperia during the day time (obviously lesser if I do alot of video playback, etc)
for #3, I doubt any phone would be able to switch tower w/o dropping the call. It's the case for any GSM phone, and I could prove that since I got a UMTS access point (equivalent of the tower except that this is a "personal" one ) at home, and once I walked out of the coverage zone, the call will drop regardless of which phone I hold.
By towers, I think he means cell towers, i.e when he is in the range of one tower, lets say while driving, then leaves that tower's range and goes oto another tower, it doesnt switch, it just drops the call.
Rory
Yep, I know where the points are on my drive when the range of one tower ends and the other begins. My previous phones could all make the transition without issue. My Xperia definitely can not. 25 minute drive = 3 towers and 2 dropped calls.
Had to soft reset twice this morning before I could get a call to go through. The phone says connecting and then connected but nothing comes through. Real pain in the butt.
Perhaps I have a defective model? Anyone else using X1a on T-mobile in US. I would like to know if it's a ROM issue that can be fixed or somehow the phone isn't compatible with T-mo US....

Sorry but you are talking crap. The whole point of the GSM standard is to get phones to carry on talking as you move location. I suggest you read about Handover (or Handoff). The Wiki page isn't the best I've seen, but it does try to explain it.

ok I stand corrected. my apologises.
I just noticed that my phone (and my wife's phone) cuts off once I move out of my home umts access point, so I assume its the same for all the cell towers. (on hindset, mine being be a scaled down cell tower so I shouldn't be using that to prove commercial one )
That said, in reading further, do you know if soft or hard handoff is generally implemented in CDMA network? I suspect it's the latter, and that probably explains why you have dropped call due to inability to switch to the new channel fast enough?

I doubt your home-hosted access point would be allowed to perform a handover with public cell tower, that's why it cuts off. It's like trying to move from one WLAN SSID to another. If you read more about handover, you'll notice that it includes a lot of security measure also. If handovering and handovered base stations are under different controller(RNC), all encryption information has to be passed from old controller to the new one, etc...
Yes, The point of GSM is that it 'hands off' the call as you pass by different cells automatically, so no dropped calls.
In fact, this is ONE reason they do not want people to use mobile phones on aeroplanes, is that since you would be on top of many towers/cells at one time, then they would be constantly changing/swapping among cells, and if there were a lot of people doing that, the chatter between the cells would be very great and overload them. Thats why they want to set up a cell on the plane itself, so that all the mobile phones talk to that cell only (as the strongest signal).
It has nothing to do with interference to the plane systems. If that was the case, it would be so easy for a terrorist to crash a plane, just bring on a radio transmitter and everyone dies.
Yes, it's the handoff that can't happen.
Othertimes, when I'm sitting in one place, I'll have 3 bars and the signal will suddenly disappear. The phone will take 15 seconds to reaquire and then it will be fine. Usually seems to happen when someone tries to call me. It's almost like the phone hasn't maintained a connection. Very annoying.

I recently moved into a new ‘cell phone death trap’ apartment (apt).
I’ve seen my phone connect, I’m guessing; connect to four different cell towers from my apt. I’ve sat and watched it go from 2 bar E, disconnect, to 1 bar G, disconnect, to no bars 3G, disconnect, and so on….
But here’s the clincher…
Sometimes it will also connect to a full strength edge network, but it indicates it’s roaming by the Triangle icon. Now if I’m on that ‘Triangle” network, my phone works great, meaning I actually can make and receive calls!
But, I’m guessing again, because it shows it is roaming; it also does not like to stay connected to this network. Actually it prefers to switch itself back onto a weak edge network without any signal.
My phone battery doesn’t last more than five hours, NOT TALKING, just in standby because it is constantly switching towers.
At this point I want to throw my Hermes out a window! But I know that wont do any good, because anyone else who come to my apt and has AT&T/Cingular gets the same results.
So here’s my question:
“Can I force my phone to stay on a particular cell tower?”
If so, I love you….
you should re-post over in this thread Daniel's software might be able to solve your problem (or Daniel might have other ideas).
thank you for the suggestion. i tried that and he said, "Sorry nop. It isnt the pourpose of cmp or bs...."
I don't think you can force to a specific tower but you can force to a particular provider:
START/SETTINGS/PHONE/NETWORK/MANUAL
and also select whether you want to force GSM/WCDMA and the GSM/UNTS band:
START/SETTINGS/PHONE/BAND
Maybe by going this route you can lock onto a reasonable signal.
2 other alternatives... Sell the appartment... Buy a landline and donate the Hermes to me

Are you able to change networks?
Are you able to ask your service provider the location of the towers and if they're planning either any upgrades or any more in the area?
If not you may wish to consider the first point, changing service providers.
I know what a pain it can be to have little or no service when needed. Personally, here in the UK, I'm on Orange. Where I lived in Wales it was either Orange or Vodafone that has a decent signal. When I'm out and about with work those are the two popular towers with o2 creeping up and some others too, but for the most part those are the strongest.
I don't, I'm sorry, have any better advice for you. Apart from leave your Hermes on charge when you're home near a window (safely) and carry a bluetooth earpeice around instead Good Luck with your Valiant Quest

I've tried this method as well and it does not help. apparently both the good and the band networks all fall under GSM(900+1800)+UMTS(2100). The other two band options never find a network.

Thank you for your suggestions. Unfortuantly im locked in a 2yr contract, thats how ****ty american cell phone companies do things. Plus, the better providers in the area dont use SIM cards (ie. Sprint/Verizon), so that would mean bye bye Hermes.
Ill will go by the Cingular store and ask about the possible service upgrade, but those fools dont really know whats what, thats why im on xda-dev!
I like the bluetooth idea, ill try find a "sweet spot" in the apt and try that method. Thanks again!
"I have dream..."
My idea just seems possible, however i cant program so who am i too.....
The idea of having blocked cell id numbers. If i could FieldTest or somehow extract the cell ids from the towers i dont want, then create a file that the phone checks against before joining a tower.....
I dont know, just a dream i suppose...
In both cases (roaming and not) are you registered in same operator?
If you're having a difficult time maintaining solid cellular reception, you might want to consider buying an external antenna. Refer to my post here regarding an antenna that can be purchased from Radio Shack. The antenna is now on clearance for $20 and the pigtail is $10. This may or may not help depending upon your location in relation to the towers, but if you try it out, let me know how it works.
Cheers
Yeah, I'm on an 18 month contract... But I'm about 8 months in now
You might even be able to get bluetooth repeaters once you find your, ahem, sweet spot

i believe so. the only reason i think it's roaming is because of the Triangle icon. But my SIM is only authorized for one operator, Cingular.
is there a better way to check?

Call your closest Radio Shack and ask if they have either of those catalog numbers in stock. Worst case scenario is that they won't, however they can check the districts perpetual stock and see how many are available, and if you ask nicely, they can have the antenna and pigtail shipped to their store so you don't have to run all over creation just to get it.
...An even worst case scenario would be if you didn't live in the US or didn't have any Radio Shacks close by.. however I might know of someone who could use their employee discount to cover shipping costs Let me know if you have any questions.

Taze,
I would also recommend that you try one of Daniel's applications - he is working on Comm Manager Pro but I think that Bandswitch will probably help you. I find similar problems to those you describe at work here in the UK with T-Mobile and my battery would often run low even during a day at work. The problem appears to have been caused by the Vario II (Hermes) spending all day jumping back and forward between networks whilst hunting for the best signal. Although the Bandswitch application (very small footprint) will not increase the signal you may find that forcing the phone to operate in a particular band helps - this is very easily achieved via the Bandswitch interface rather than going into settings each time. I now regularly switch to GSM each day when I get to work and it has solved my battery run-down issue completely!
Comm Manager Pro does much the same and more. It allows you to define a location (according to Cell ID and LAC Code) from which you can set the CMP application to (amongst other functions) switch to a particular band - or even turn the phone off).
Given what you have said this may not help but I would certainly give it a go. Good luck.
Regards

im going to try bandswitch today and see how it works. thank you for the suggestion!
i wish daniel could add the feature of blocked, preferred, of locked Cell ID's. that would be worth a good amount of money to me....
Hi.
I would like to help you.... I can detect cells and lac but I cant force radio hardware to attach on a particular cell. This a task for Radio ROM. The only posibility (maybe) would be if the operator names are diferent. Could you go to settings a search for operators? Maybe your operator has different name in roaming than non roaming. In that case It would be easy to help you....
Oooo if FieldTest were a controllable application....
Ok what I’ve discovered so far after watching FieldTest for about an hour.
The Good Connection -
LAC 0020
MNC/MCC 31017
NCELL INFO1 700-80 dbm <---- (at least four out of six NCELL maintain a steady 700-80dbm, often all six NCELL)
NCELL INFO2 700-80 dbm
NCELL INFO3 700-80 dbm
NCELL INFO4 700-80 dbm
NCELL INFO5 700-80 dbm
NCELL INFO6 700-80 dbm
BAND 2CS
CHANNEL 1:CCCH (stays, doesn’t change)
The Bad Connection
LAC d6ef
MNC/MCC 31380
NCELL INFO1 140-100 dbm
NCELL INFO2 140-100 dbm <---- (i get two NCELL at the most 140 each, rarely four NCELL, never more)
NCELL INFO3 0
NCELL INFO4 0
NCELL INFO5 0
NCELL INFO6 0
BAND 3:850 (once I saw it switch to PCS on this same MNC)
CHANNEL 1:CCCH/0:BCCH/255<UNKNOWN> (switches between these quite frequently)
So what I’ve interpreted from all that is.
Well I’ve confirmed my ****ty connection. Even though the phone often shows two bars, I can’t make or receive calls. Based on the NCELL db numbers and the constant channel changing, that **** just don’t work.
Most importantly, the phone is always trying to switch to the highest possible band. Because PCS is a lower band than GSM 850, my phone won’t stay on the PCS connection.
O yes, another discovery is, in WM6, if you are connected to a PCS band network, it displays the Triangle icon as if you are roaming but in fact it is not roaming.
So Daniel since you seem to be the best chance for a better life [for my Hermes]:
I need a way to force band selection beyond just GSM and UMTS.
I tried BandSwitch and it does not work for me because all my available connections fall under GSM.
And even beyond that I’d like to be able to force MNC’s, as I believe they are the specific network number.
Or can I block a LAC?
In settings, I only have one operator, Cingular, “Home of the most dropped calls.”
Hi.
I undestand perfectly your frustration and I will try to do what I can althought It doesnt seem easy thing because there isnt any(known) api to manage Radio Rom. Fieldtest is OEM dependent and I imagine It only works for only one manufacturer of radio hardware chip.
Ok, first try. If you start radio phone 10 times....
1) how many times your phone register to roaming (and wished) network?
2) If registed to roaming network, how much time (aprox) stays on it before register to bad cells?.
Why? well ,CMP executes actions when you enter on some place (compound by cells and lacs). You could create a place with your hated cells and then associate the action "reset radio" when registed to those cells (or lacs). In this way if your device falls into bad cells it would be resetted (only radio, not phone) until registed to good cells...
Only an idea....
Dani
If you can determine the direction of the "bad" towers, try lining your walls with lead sheets to block their signals and letting you connect to a prefered tower.
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.
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.

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

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.

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
I'm using HD2 since 25 march. Stock room. So far no problems.
Chicago & east sub.
No problems here... Ever...
Louisville, KY
I have trying to use the HD2 over the last 3 days and getting real problems with intermittent signal loss.
I know i have low signal from the mobile operator in some parts of my home but that has never been a problem with other HTC phones i used before. If the signal was too weak it would just drop out but come back if i moved a bit.
With the HD2 once the signal indicator turns red it stays that way even if i move to a strong signal area.
The weird thing is sometimes i would leave the phone sitting in one place with four bars and then minutes later it would show up with no signal and i can't receive calls.
Even stranger is that in all these cases where there is no apparent signal, all i need to do is press the send button to try making a call and the signal "magically" re-appears and all is fine. I've tried at least four differnt radios as well as the energy ROM ... no change.
Any ideas ? this is reaallly frustrating!!!!!!
do the problems resemble what I experienced here?:

change radio ROM, well experiment with several of them by trial and error (read the sticky/tutorial first).
OR
buy an indoor signal booster.
Well, regardless of the radio version ive had really odd intermitant service.
the best way ive found to help this is turn off 3G / HSDPA
Doing this forces the device to remain on GPRS, it means the battery lasts a hell of a lot longer and it doent drop the connection every time the device feels like trying to connect with HSDPA or drops it for no apparent reason.

it seem that you were losing data connection .... i'm a lot worse off ... i lose data AND voice .. all connectivity ... so i don't receive calls
as i said the weird thing is as soon as press send to initiate a call,cthe signal bars come back and everything works fine!!
as i said, stop 3G from working, when switching between the two due to what ever reason the HD2 decides to drop it will kill your connection, voice and all until it switches back. there is an issue with 3G and im wondering if its everyone or just folk using TMOUS radio and thus recieving the extra RAM
To disable 3G/HSDPA to test,
Open Comm Manager and click on Phone (not the on/off switch) to go to phone options. Scroll to bottom and select BAND. Switch network type from Auto to GSM.
3G/HSDPA is only needed for internet surfing. Time, weather, stock updates and email downloads don't really benefit from it. So turning it off this way will make these type data connections go through the EDGE network which is plenty fast enough for it. When you need to surf the net, go back and switch it to Auto and you will get 3G or faster speeds for that.

hello im having the same problem..no voice or data i push my send button an then i get signal,my wife has a hd7 and my son has a hd2 they will have 3 to 4 bars and i show no signal.push talk and i get 1 to 2 bars.
have you found a fix?
You could always try a signal booster on eBay for like 5...

If its just 3G then its probable just T-Mobile or then again a Hardware/Firmware issue
try a different ROM, Radio
I have this same issue I running a T-Mobile USA (using radio 2.12 but then again it was doing it on 2.15 as well) and it just drops all connectivity and says no service I have to search the network again.
My phone is unlocked I don't know if that might have anything to do with it as well
I've had this problem on my HD2 since i got it.
Edge (E), works but slow as all get out. 2-4s ping times or time outs. 3G (and when i say 3G i mean when it says 3G in the status bar) doesn't work at all. HSDPA (H) works great, WHEN it stays that way, which it doesn't.
It can switch between 3G to H every 10 seconds.
And i'm using it for tethering primarily, which makes working painful. Lose your VPN and SSH sessions constantly. Some days it's ok. But most, horrible. btw, i'm in the Denver area.
I've tried stock roms and custom roms (primarily Energy). All radios. Nothing fixes it!
This is the only thing I don't like about my HD2 and/or t-mobile. And it's a whopper. I'm almost ready to get another phone or carrier, depending on what's causing this.

I have 4 HD2's with one having the problem you describe and have come to the conclusion it's a hardware issue. Probably a cold solder joint on the antenna lead.
In WinMo or Android the signal bars jump all over the place but the signal level in 'about phone' shows a constant signal even though the bars show nothing. I don't drop to many calls but miss more than a few incoming. I travel for 5-8 hrs in the same area everyday and very familiar of good and bad areas of reception. I have tried stock/cooked ROM's/Radio's with no noticeable difference.
I'll probably send mine in to HTC to be looked at.
Bit of an odd one. Basically at home with the phone on my home network T-Mobile I simply can't get a GPS fix. This problem has only happened in the last couple of weeks previously its been fine, a fix within seconds.
As some of you may know T-Mobile and Orange in the UK have now enabled roaming between the 2 networks. If I force the phone to roam onto Orange I get a GPS fix with-in a minute. Switch the network back to T-Mobile back to no fix.
If I'm in a different area, network on T-Mobile, fix within seconds. I thought maybe it's quick GPS wrongly loading the wrong area because of an issue in the cell db, I've set quick GPS to never update and now the GPS appears to cold start although quick GPS still says the data it has is valid for x number of days.
I've tried defaulting the phone but exactly the same with defaults and using GPS Test rather than TomTom.
Does anyone have any ideas? Is anyone else having the same issue?
I just tried another test. I roamed onto Orange and got a GPS fix in TomTom, I then set my network back to T-Mobile and the GPS fix was lost! As I switched networks I left TomTom running in the background.
A bit more testing. If I force the phone onto 3G T-Mobile the GPS works fine. My theory is what ever frequency the cell here operates on (some 5 miles away in the 1800MHz band) must be causing the some issue with the hardware
I'm thinking that most people wouldn't be able to experiment to see this, I'm just lucky or unlucky depending on how you look at it that I'm in a position where I can switch networks therefore changing frequency within the 1800MHz band and I can stay in the same place to test it. I've had in the past where the GPS would loose its fix for no reason and then just come back while travelling on a motorway I wonder if this was the same thing. Also the chances of someone owning a HD2 using the GPS and being on a cell who's frequency causes a problem is pretty small, and if your travelling you're likely to just think it's dropped for some reason, and oh yes it's back again now so think no more of it.
You are getting confused between GPS and GPRS.
GPS is the satellite system that you use to pinpoint your location (as with TomTom). If your phone is indoors or has a restricted view of the sky, then it cannot receive a signal.
GPRS is a data connection between your phone and the telecoms company. It is basically 2.5G, which way a intermediate step before 3G became set up.

No, completely understand the difference between GPRS and GPS
I've proven with out a doubt that when using the t-mobile cell serving our house (2g) there is no GPS signal. Use another network still 1800 and there is GPS, use 3g, or move to another area on t-mobile there is GPS.
GPS was working at home while on t-mobile upto a couple of weeks ago, I can only think that the cell has had some work done and has changed frequency.

Silly question, but have you got AGPS activated? Because it can give you a rough location based upon the local cell transmitter info and any GPS satelite signals you may be recieving.

I have AGPS disabled. I doubt my operator supports it. I have tried with QuickGPS disabled and enabled but makes no difference.
If I get a fix while on Orange, leave which ever GPS enabled application I have running, running in the background, force the phone back onto my home network (TMobile), go back to the GPS application there's no fix and no satellite signal being received not even a hint.
I've also tried with the SIM card removed and GPS performs perfectly!
Thank you, I thought I was going mad - my GPS has been working perfectly since I got the phone 6 months ago but in the last week has been dropping out or refusing to start at all.
I tried a hard reset, which fixed the problem until I started driving the next day - after a few minutes TomTom lost it's way. Using a bluetooth GPS proved the signal was good, so I was coming around to the idea that the phone was broken...
I have also now read other users that have had GPS problems when roaming, although usually when switching between countries.
Looking on the T-Mobile website about the orange roaming issue it say 'there might be a few quirky side-effects' but I haven't even signed up for the Orange roaming option, sounds like T-Mobile has changed something for everyone?
I have read that fixing the network choice to manual, not auto, can help with GPS issues while roaming - I've yet to test this.

I've had the issue for a couple of weeks I would say. Certainly last weekend I couldn't get a fix for ages when I set off and it wasn't until I was a way away from home that the GPS got a fix. This was before the roaming got switch on, of course it doesn't mean they were not doing something with the cell/network.
I too can get a perfect fix with external GPS or with a GPS nav system, or by changing networks! I've also tried another SIM card in the phone, again T-Mobile and get the same results.
I've attached some screen shots.
1st T-mobile no satellites, you'll notice that there isn't so much of hint of signal.
2nd Changing network.
3rd T-Mobile Orange and GPS fix.
All screen shots were taken with the phone in the same place.
Just come back from a drive just to test the GPS. Basically driven 30 miles away from home fixing the phone to T-Mobile and 2G and the only time I got a GPS fix was when the phone lost signal.
Parked in a layby and switched over to orange and got a fix with in a few seconds! Just can't figure out what the connection with being on T-mobile 2g is!
What Radio version is your phone using?

Have the same issue with various official T-Mobile ROMs.
I had a play with updating my AGPS settings last night using the Google settings from this thread: http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=544421 when working on Orange couldn't notice any difference, with T-Mobile still not GPS fix.
I left the GPS running over night on T-Mobile, admittedly indoors but somewhere I know I get a fix, there was still no fix 7 hours later.
I live in a rural village covered only by one cell mast. GPS starts and runs fine at home with or without the phone turned on. if I walk over the other side of the hill, different cell mast, the GPS drops out immediately - I can't test if 3G fixes the problem as it doesn't work here. Once the GPS has stopped I can't get it to start again, even switching the phone off to airplane mode doesn't help. Only a soft reset, with the phone still in airplane mode will allow the GPS to start.
Switching the phone back on and the GPS drops, however walking back over the hill to home - back to my original cell mast and the GPS starts again.
I'm pretty sure t-mobile have rolled out a change to their 2G system, but not to all masts? rural ones maybe last done hence why my home cell still works.
How to proceed from here? T-Mobile are kind of hard to talk to.....
One thing I did notice was in Memory Map the satellite view normally flicks across satellite numbers until it finds a signal, if the T-Mobile problem occurs this process stops and it would appear to have frozen the service?
I take back the hard to talk to part of my last post, I emailed support from the website and they phoned me back within 2 hours!
As to be expected they couldn't give any instant answers but I gave this thread as a reference and the problem is to be escalated.
The call centerthen phoned me back and asked if I was happy, also to offer me 30 minutes free calls for next 3 months - very nice thank you.
Good work boomboomer. Hopefully T-mobile will find something. I'd like to know what they find, still can't understand the connection between a GSM network and GPS though. I haven't tried a controlled test with flight mode but will try that later. Out of interest what part of the country are you in? maybe it's just a pocket of cells that are affective? I'm in the BA8 postcode area.
The problem certainly only affects 2G, 3G is fine.
I'm out of the country this week but fingers crossed T-Mobile will find the problem. It's nice to know I'm not the only one with a problem.
I'm quite a distance away, DT2 here.
I've been asked to test the GPS over the next few days and keep a log of when and where it doesn't work, they said their network people will ring me soon.
At least this fault is 'interesting' in the words of their technical support guy, he'd never heard of anything like it, so there's hope they will give it some time.
On the plus side they've also given me a free month of internet, so I can't fault their customer support focus.
Incidentally, do you have SPB shell installed? This was the only change I'd made on my phone at the time this problem started.

I didn't get chance to do any testing today at Heathrow as ended up being a bit rushed. I wouldn't say your not a million miles away. 22miles ish, the Cell that covers our home is in Dorset which is pretty useless when you have to call 999 because you get connected to Dorset who then can't pass you to Somerset and you end up being in a situation where you have no way of contacting Somerset 999 not great in this day and age! But I'm not going to get started on that one on this topic.
It's quite possible its a regional problem.
No I haven't installed SPB shell, I have tried it with a defaulted phone but still had the same problem.
I'm out the country now until Friday, but will do some testing when I return on my return journey. I'll fix the phone to 2g T-mobile and keep an eye on where the GPS drops out.
Oh dear, just got a call from T-Mobile technical networks - they don't support GPS as part of their service and won't be spending any time on the problem, case closed. They did say the problem seems to be with HTC devices only, blackberrys are not effected so it sounds like they have heard of the issue eleswhere?
Looks like it's a network switch required to solve the problem, shame that as I've been with T-Mobile for over 7 years.

Hmm, T-Mobile sold me the phone for use on their network, the phone is sold with a GPS, that now doesn't work on their network surely they need to spend sometime working with HTC to resolve the problem.
I do have a case open with HTC under the ref 10gbc410001235 they were supposed to be taking it up with tier 2 but as yet I've not heard anything back. I'll have to follow it up when I'm back in the UK. It might be worth you also logging a fault with HTC quoting my ref. at least if 2 people call in with the same problem they may start to think it's not just one crazy with the issue!
My other half has a HTC Desire, I haven't checked the GPS on her phone. Not sure if they use the same chipset, of course one is WM the other android. I wonder if its a problem for all HTC phones or just the HD2?
