Connection Issue (AT&T) Help! - Touch Dual, MDA Touch Plus General

I have had my dual for the past 3 weeks and it has done great (even with out 850 on the AT&T network).
Yesterday I took a driving trip to another location (about 2 hrs). The entire trip down I was monitoring the connection on the phone and it had ok connect. At one point I made a call on the phone and it was great call quality. About 20 min later I went to make another call and the phone had not connect (radio Icon with constant dots or !). I thought I had just wandered into an 850 zone. So the entire drive back I had no connection (where I had had it on the way down). Even at my house I have no connect. It will not connect with the AT&T network anymore. I called AT&T and "registered" my IMEI number just in case they had locked me out (they said they did not).
I have taken my SIM out of my Dual and put it into my Cingular 8125 phone and it works like a champ.
I have also done a hard reset on the Dual.
I hope I did not throw $$ power the toilet.
Any Thoughts??? Any logs to look at??

had the same problem on the first day I got the phone. wasn't roaming like you tho. Signal came right back after a soft reset. haven't had this problem since then. it's been a wk.

Same with O2-Germany
Same issue here. Using my Dual for 2 days now. Everything worked like a charm (phone, 3G-internet) and then I was travelling by tram (few km) while surfing and then... you know it.
No connection for several hours, network scan shows all available networks, but connecting failes. Several soft-resets didn't help either. Done a hard-reset a minute ago: didn't help. Using the same SIM in my old Magician I experience nothing but a fully working phone.
So... I gotta return that Dual to O2-Germany tomorrow, hoping to get a working one soon.
Cheers,
jekk.
//update
just got connection after a soft-reset.. but... here is how:
1. soft-reset
2. entering PIN
3. Dual searches...
4. And after 3-4 seconds, it connects!
5. after again 3 seconds it recognizes 3G
6. after another 3 seconds it looses the connection. Damn sh*t.
// another edit... looks like this is becoming a monologue, uhm?
Since I do not want to give my Dual back to O2 I searched a bit and have come to this solution:
Changing the phone settings does the job. Go to Settings->Phone->Band and choose the appropriate values. In my case there are W-CDMA issues, since sticking to GSM solves my problem. Nevertheless, this is not the way I wanted to use the Dual, if I CAN have 384kbit (no HSDPA around), i WANT it. End of story.
Tomorrow I'll tell O2. I promise.
// update 3
This is obiously turning into a monologue now, but now I know why:
This wasn't an issue with the device. After calling the hotline several times, it turned out that my access-rights to the umts network were altered accidently. The man on the phone did a usual check of this today and changed it instantly and after some minutes the problem and was gone. So to summarize:
Everything is fine with my touch dual.

Exec looses signal

Hi guys,
ive had my exec for about 2 weeks now. In the last week it has started to randomly loose network signal. It keeps searching till you either soft reset it or turn flight mode on and off. It will find a signal in about 10 seconds after that.
Is this there a 'dont keep loosing signal' setting that im missing?!
Mine does the same thing - annoying as hell! Not worked it out yet.
Are you talking about telephone or GPRS signal ( U or G )
Phone signal
everything! it looses all signal.
I called o2 and they want me to go into an 02 shop for them to have a look at it before they give me a replacement
The are all 'handset trained' apparently.
I also called o2 a week ago stating the same problem, They gave me a refferance number and said they will look into it, But of corse 1 week later they have not called me, So this afternoon i will find the referance number and give them a call.
I will post ther Bollox answer on here tonight

Same problem here with a MDA Pro. I ahve noticed that this happens when I am roaming in Germany as well. Very anoying. That and the thing freezing in a call and needing a re-set. This is my second one as the first one the screen portion became loose, happened on the one before as well.
I have the same problem althoughmine will refind the signal after about a minute. It seems to disappear whenever I ask thephoneto do something new (open a program etc).
I finally persauded T-Mobile to exchange mine so I'm getting a new one delivered tomorrow.
I'll let you know if that fixes it!
Andy
My XDA2 used to lose its ability to communicate if I was out of a signal area for more than 15 minutes, but I haven't had it happen yet with the Exec. A soft reset or Flight Mode on/off cycle would fix it.
It is frustrating but didn't happen often.
Well i phoned o2 and they said there was still no answer and that no one else had complainded about this, So i told them of this forum......
As per the last post i have also had this on a 2 and 2i, and i gree if its out of servie for a few mins its seems to give up looking for service until you reset.
mine has done it overnight befor, i looked befor going to bed and it had just the 3 dots flashing where the aerial should be. the next morning it was still the same, quick soft rest and into full service, thats when i first rang o2
John
I've had this on all my XDAs in the past, and seems to continue with the Exec.
Very annoying, but not sure what can be done about it.
Ant
guys,
wait for a rom upgrade from o2, ( with new radio rom)
that should solve the problem.
happens with xda, xda2, skipped xda2-i and xda2-s,
and now it's back.. :roll:
Hi Guys, I have been having this problem for weeks with my MDA Pro. I convinced myself it wasn't the phone and that it was T-Mobiles Network. In desperation last night I spoke to T-Mobile about the problem. They told me it was a faulty phone and that I would have to contact the supplier of the phone and ask them to replace it. I tried to explain others had the problem and that I wasn't happy to have to send my phone off and wait for a replacement. But no avail. So I sat down at home and looked at the settings. I think I might of cured it! Maybe it is a fluke but by clicking the signal meter and going to settings, then changing network selection to manual it has stopped hunting when it loses signal and quickly re-picks it up. HNope this helps others.

Defenitely...that did it.
I had the same in Holland with KPN: while switched to manual no more problems.
In Romania however, where I also have UMTS, I had to switch it back (or it switched itselve back, after changing SIM card, I don't remember) to AUTO.
There it switches from GPRS to UMTS if UMTS signal is OK.
Huib
Ok, i have the same problem. Have GPRS Always on set in registry and 10 minutes ago, my MDA Pro lost GPRS connection. It trys to reconnect all the time. But no Connection can be build up. After Flight Mode and back, i get a connection immediately. But on start of MSN Messenger, it loses the connection again and does the same loop like before. Only a softreset brings my connection back to live.
Looks like a ROM issue. Maybe GSM or CE.
I am delighted to say that my replacement MDA Pro seems much more stable in the signal department. Although I still loose signal ocaasionally, I no beleive that is due to poor signal area and not the phone...
If you phone isloosing and reconnecting all the time then like mine it is probably faulty! Hopefully the ROM upgrades will sort out the last few issues I'm having!!
I love this phone!!
Same problem with JASJAR
People still have this problem? i'm using radio 1.03.01. When i used the original firmware, the phone part would lock up (Would get the busy - wait 15 seconds and try again, but it would never clear - had to soft reset)
With the 1.03.01 radio, i still get disconnected, but it'll find the signal again after a few retries - which is very bad! I rely on the phone at work, and people can't get through when it's disconnected. I have full signal strength (4 bars) so it's a software/hardware problem.
It looks like maybe it happens more frequently when charging or activesync'ing, than when it's disconnected from usb.
Can anyone confirm having the same problem, and it getting better or FIXED with the new radio firmware? If not, i'm going to have to return it.
Michael
I am using radio version 1.04.02 on the O2 exec, although i use a Vodafone SIM (supplied by work!). Mine suffers from the same problem, mainly at home, which is a very odd signal area for Vodafone. I can go from no signal to full signal to none again, and yes, sometimes it drops completely and needs a soft reset - bingo! full signal again.
Switching the network type from auto to GSM does seem to make the unit a little happier, but i need to use WCDMA when possible, so i leave mine on auto and live with the dropouts!
Lets hope the next rom fixes the problem.
Cheers
Paul
I have the same problem with my XDA and O2. a soft reset nor a full reset have been able to fix the problem. :roll: is the new rom version available as yet?

Phone - The operation failed.

Quite often these days I am getting the issue mentioned above. Even soft resets do not seem to help. Until I reset a few more times.
What might be the cause of this? Thanks.
Hope someone might be able to assist on this. Thanks.
I'm also getting this message nearly every time I try to make a call. The phone then looks like it resets the connection with the cell tower and it successfully completes the call on the second try. Then the next time I try to call someone else it fails again. I came to this forum to see if anyone else has experienced the same problem.
Hey joej, I found out what might be causing the problem: make sure that your ActiveSync is closed before you try making a call. That fixed the problem for me.
Also, here's a quote from an email from one of my coworkers:
"Your Tytn was probably trying to dial a data connection at the same time that you were trying to dial voice and so it has to cancel the data request before you can dial out. There is a registry tweak you can do to the Tytn to keep the data connection always active when the phone is not in use and this may make it less frequent that you would have a problem
Activesync is supposed to stop when your data connection is unavailable. If you are making or receiving a call on the TyTN (or any GSM phone) your data connection will not be available and therefore not run. Do you have a lot of 3rd party apps running at startup as well? I have rarely had a problem with my Tytn and never during a call unless my battery dies on my BT headset mid call and then the device may get confused."
Hope this helps!

thanks for the update, i however am experiencing this issue once in a while and it is not with the activesync running nor a data connection going on. ugh..... guess mine is odd
Me too
Thank so much for the post count me in there too. I am southern central PA and just last week this started happening to me too. I have an 8525.
I have no acrive data connection nor any apps running that force a data connection. Every morning I have been resetting the phone 5-6 times before the freezing stops and it works. So annoying.
I am suspecting it is a network issue with cingular and them upgrading to 3g in my area. I suspect it as I had to travel north this week and discovered 3g coverage in Harrisburg so I am betting that is it.
I feel your pain and I have no fool proof thing to do on the phone to fix it. But man the phone on the 3g is fantastic.

yup, everything rocks in it except the phone functionality really needs to be improved to be more usable.
do you know how i can use the phonepad to do t9 for replying SMS ? right now i am finding it hard to do so as i need to use the normal input methods which is not as easy as a normal cellphone
omg I'm from Singapore using Starhub think I'm having the same problem too. Dopod 838 pro.
A soft reset works for me, but very frustrating coz you dunno whether you are missing calls - the screen shows mobile is up with signal and all but people can't call in.
Just started happening to me past few days but then again I just took over the phone from a friend who bought it 3 months ago (latest batch)
So frustrating. ... seems related to the activesync.. but then again still happens when activesync's not involved.

Same here anytime Cingy plays with towers, have you ever got a message stating the call can not be completed at this time? Been getting that one lately as well.
I think that it could be an issue with the phone heightened by the nature of the cell network.
I am wondering if the phone has issues handing off between cell towers as I have the band tab active and there are freq choices so I wonder if the phone even on gsm has some issues dealing with hand offs.
I locked it on gsm and still had issues with the phone. I locked it on 850 and still had phone issues. Put it in auto for the freq and still had issues.
On the U network on Cingular since its the only one the phone is excellent. Data and voice work great. So it will get better in the US for us on Cingular. But man its going to be really annoying during the roll out.
I'm on T-Mobile and I'm seeing this problem as well. (It didn't go away after closing ActiveSync like I said it did earlier.) The weird thing is that this wasn't a problem until about a week or two ago; now all of the sudden it's happening constantly.
Also, I just installed the newest HTC ROM (1.35.255.2) yesterday and now my phone has started to drop calls. I've never had a problem with dropped calls in the 2.5 years I've lived in this apartment.
Ain't technology grand?
Well things have not improved for me. Today after 8 resets the phone finally settled down and did not freeze and was able to get on the network. It has been terrible for me the last 2 weeks...
I removed the eten dialer skin I was using. I wanted to make sure it was not due to replacing the Cingular phone skin.
We shall see tomorrow if the phone is able to work without multiple resets..
If not it is off to a hard reset and re-load to see if that improves it any...
I have taken the plunge and did a hard reset plus reinstall of everything. I had the same apps installed again and the problem seems to be gone now. *touch wood* hopefully this doesn't come again... a restore takes too long. I have also installed Sprite and did a full backup of the phone including the memory card just to be safe.
This problem started for me this morning. (NYC/NJ Area - USA). I did a hard reset (actually, two) this morning, and it didn't fix it, even when the phone first finished the initial load (in a virgin state). Then, around 11:00am, it began to work again. Now, it's about 6:30pm, and I need the phone to call home to tell them I'm gonna be late, and it's out again. Seems like it's something not to do with the phone, but with the network (I hope). It won't connect in GSM, UMTS, or AUTO modes, FWIW.
Oh well, sure hope it doesn't takle two weeks to "go away".
returned
Well I returned mine. Did the warrenty exchange. So far so good. No freezing and the phone seems to hold onto the network ok now.
I truly believe mine was defective. As the phone would show searching and not connect to the network.
I think that not being able to make a data connection is a network issue as it clears up in a few days.

also in the same area, experiencing similar problems within certain specific locations. Noteably these are locations that I get SPOTTY UMTS service, so I assume a tower upgrade is in progress or something that is causing this. Where I have full umts service, the problem does not occur.
at times i have signal, but calls don't come through (rings to calling party, but goes to voicemail before my device rings).
This is something related to 3G because when the sim is put in a blackberry 8700c, everything works A-OK.
Glad to know i am not alone in this
I have similar problems. Especially in the university of Hannover. There is UMTS. Since a few days Data Connections via Active Sync don't work.
Before I had problems with calls. For example freezing during call.
And of course in the university and on other places I have often to do calls twice.
I called O2 for that problem. They are upgrading the cell around the university to HSDPA.
Hi to all !
I had the same problems, then i removed the microSD card and the problem was gone. Now i am testing the phone without miroSD card. I forgot to say that i had the problems with boot too(No GSM) and now it boot perfectly.
Best regards
O2 XDA Trion (dopod rom)
I finally had to return the phone under warrenty. It degraded to no gsm all the time fresh from a hard reset with no mem card. The new device has been flawless radio wise for a week now.
Problems with XDA Trion SOLVED !!!
Hi again !
The microSD card was NOT the problem ! I tested the phone without SD card but that was not the problem. Then i go to my provider and change the SIM card with new one (the old one was very old so i buy new one) and wauuu it works. The XDA TRION needs the sim card with UMTS suport then it will work fine. So far NO freezing at all. I will let you know in a few days if something strange will hapen.
Best regards
Hi, to all with the problem “The operation failed” when trying to make a call:
Try to switch off bluetooth (specially if you are in UMTS (CMDA) network) and then try to make a phonecall again.
For me this helped to solve it.
First I also thought that it’s only a Provider network problem (I have 2 different providers, with one it works, with the other I have the “operation failed” problems).
So it is 100% a phone software problem. (Shame to HTC)
Give feedback if it helped you too.

Trouble with signal/Service

Hi,
First of all, I've been reading on these forums for MONTHS and have enjoyed ALOT of great information and software from the people in here. Unfortunatively I have not had much to contribute with, so I skipped the part of registering a user..
So, thanks you all the great stuff, keep it coming!
Now over to my big problem, that I really hope you guys (and girls?) may help out with..
First a bit of story (if you're not bothered, skip this part!).
I went to Miami, FL in February - and my phone back then, iPhone 3G worked flawlessly before and during the trip. Then, 3 days after I came back home it started pulling jokes on me, not connecting to the network etc.. So I get a replacement.. Then, the next time I went over, with a Nokia E63, I bought a T-mobile G1 that I unlocked and got working when I got back home to Norway. 3 days after I came back home the Nokia said no thanks and stopped functioning in the same way as the iPhone. Well, I had the G1, so I just used that one.
Well, I went to the states again, this time to California, Arizona and Nevada with my G1 as travel buddy! It has worked flawlessly all the time before and during the trip, but 3 days after I came home it stopped functioning. I get the "No Service" message with different SIM cards, it doesn't show me that hardware IDs of bluetooth and WiFi (Same as on the iPhone). But WiFi and bluetooth still works - its just the regular GSM/3G network part that doesnt work...
Well, to hell with it - I reflashed the thing with the newest radio and the newest custom ADP software (dont remember which custom one), and it is still not working quite well. No network at all!
I can post a bit more details about firmware and baseband/modem software later on when I get back home and can check out the phone - but it is really frustrating! Right now I got a Nokia E71 off work to use - but after a couple of days I really miss the Android!
I am pretty sure this is a SW issue, as the phone has been taken really good care of, never been dropped or in wet weather..
Any help, tips and hint will be GREATLY appreciated.

did u reconfigure your apns whenever u switched sim cards?
Same provider, different SIM cards and numbers, so shouldn't need to do that..
find out which ROM you're using. also double check which radio you have, cupcake builds tend to use the radio ending in .26I, there are some donut builds having a few issues with the radio, but these should be fixed soon. also even if you're using the same network, for example t-mobile, sim card regions can make a difference to the APN settings. such as a UK sim uses settings specific to the UK, while US sim would use US settings. normally this isn't much of a problem, but the developer of your rom may have missed out the APN list so you would have missing APNs. doesn't hurt to check
hope it helps in some way
Hi!
Sorry I used so long, I have been busy at work lately.
My version numbers are:
Model Number: Android Dev Phone 1
Baseband: 62.505.20.17H_2.22.19.26I
Kernel version: 2.6.27.00392-g8312baf ([email protected])
Build Number:
dream_devphone-userdebug 1.5 CRB21 147201 test-keys.
Under status I get the following (Which I also got with my old firmware/baseband - without any warning at all!):
Phone number: Unknown
Network: Unknown
Signal Strenght: 0 dBm 0 asu
Mobile Network type: unknown
Service state: Out of service
Roaming: Not roaming
Mobile network state: Disconnected
Wifi works, but there is no way of accessing the Telenor network, as it gives an error message saying an error occured.
any tips will be perfect!
no one?
i've had a similar issue
i lost signal all of a sudden without any reason......tried restarting , reflashing.... nothing helped. After about an hour, signal was back, i'm sure it wasnt the network because checked with a few people while my signal was out
Now to the interesting stuff, i've had exactly same issue with htc touch diamond, both diamond & g1 share the same hardware platform and i'm seriously begining to doubt qualcomm's chipsets
Do you know what chipset is in the iPhone 3G as it happened to me on that one aswell?
And, to me it sounds even more suspicious that this happened just a few days after I came back from the states both times.
And I've had a SIM card in the G1, turned on since my first post, and there is no sign of service at all any of that time - as it would have recieved a copy of SMS's sent to my Twin SIM in the E71.
Well, I better just bite the lemon and get myself something new and more useful.

HD2 no signal, shows exclamation

Hi everyone, my HD2 just stopped working with no signal at all.and shows a exclamation all the time, sim cards are no problem. i've updated the phone with official sw, still have this problem at the beginning.
has the phone been blacklisted?
is the phone turned on in wireless mode in settings? ( ya never no)
is it still under warranty?
My HD2 has done the exact same thing, just shows an !
it doesnt even try to find a signal.
phone was a tmobile UK version, which was unlocked to use any network.
the problem has literly just happened today.
have tried different offical roms, and different sim cards.

Just phoned my provider in regards to my phone, quoted the emei and have been told the phone is blacklisted.
they are sending a request to have it unbarred. will post the outcome.
I have had this happen alot with Vodaphone UK. This is a brand new number so doubt it has been black listed.
I can get this working my turning the phone to airplane mode then back to phone mode, this most of the time makes the phone look for a signal.
Usually happens to me when there is no signal like in a tunnel, the phone does not seem to try looking for the network until you force it to.
This is possibly a fault with the timeout of the HTC HD2. Could be once it tries to connect when out of signal the device gives up after a number of attemtps.
Does anyone know?t

Usually happens to me when there is no signal like in a tunnel, the phone does not seem to try looking for the network until you force it to.

I was searching before posting for just this problem.
It is really irritating me. The phone can jump from deciding there is no signal to sometimes even going to full-bar "H"!
I hav currently resorted to turning off 3G as at least that way I am eliminating the idiocy of it prefering 0/1 bar of "H" vs near full non-3G reception for calls.
Even so at times it will just sit there for ages having dropped a signal with the exclamation showing and then jump back to life [in the same place] with good reception.
I am also on Voda UK
Mine has done that twice, in 4 months. 1 time phone was turned off inside connections, no idea how? 2nd time I just shut off, & back on, signal was back, hasn't happened in months now?
so does anyone have a solution to this problem?
I've checked with my service provider and my phone is not blacklisted...
My SIM card seems fine and everything else seems fine, except it keeps giving me the exclamation mark.. most of the time i notice it's when i get out of the lift (but that could be because that's when i usually check my phone before I put it on my desk).
There are many occasions (probably 5+ times/day) where I turn my phone on (ie, off standby) after it's been sitting on my desk for an hour or so to check calls, etc and there is that dreaded exclamation mark.
I know the area around my desk does have a signal because the guy next to me on the same network has a strong 3G and 2G signal.
Sometimes going to Comms to turn airplane mode on and off to force it to look for a signal works, but sometimes it doesnt.
I've tried soft-resetting, hard-resetting, using different radios, different ROMs, etc and still no good.
Funny thing is, it's only been happening over the past 2-3 weeks.. and I'm not sure what triggered it.
It's really starting to frustrate the crap outta me and friends have been asking why they can't get through...
Any help would be appreciated.. . I'm trying to avoid sending it to the HTC service centre if I can because they're slooooow and the stories I've read about my local centre are pretty bad (when I had my HTC diamond).
Solved:upgrade your rom everything gonna b in place
Upgrade to what?
I am having the same problem, for a hile now. Been fiddling with phone settings parameters, trying to see the effect. One particular combination so far seems to work. Try this: Comm manager --> Phone --> Tap Change Phone settings --> Menu --> Advanced network --> GPRS --> select CHAP authentication --> then CSD Line Type --> select Data rate 9600(v.110). Then OK, Back, and Done with the Comm manager. Observe if the network pickup performance (switching from non-existent H or 3G to E or G) works better for you after that. It does better for me, so far.
I'm having the same problem - NO SIGNAL
Any solution?
i recently discovered that for my problem, it was to do with the earphones. Not sure why, but it only seems to happen to me not long after i plug or unplug the earphones.
I usually have my HD2 on my desk with the music going while I work, but every hour or so, I unplug the earphones and take my phone by itself out with me for a cigarette.. then I come back and plug the earphones back in.
Often when I'm about to head downstairs, I turn on the screen while the music is still going and i see the "!"... as soon as I unplug the earphones, the bars indicating reception comes back straightaway!
Not sure if it's a coincidence or whether it really does have something to do with the earphone/earphone jack.
Since I upgraded to the Vodafone rom on the htc website I have not had this problem

I have just bitten the bullet and accepted the phone is crap at swithing between 2G and 3G signal so turn off 3G in a couple of locations when I know I get this problem [home - I can use WIFI] and my office.
HTC would not be drawn at all on un updated Radio and this problem being "fixed" in USA ROMs
Fixed
the very easy fix is to do this :
settings _ personal _ phone _ network then make network selection to manual ,, then choose ur provider,,, then u will have signal,, after that u can turn it back to automatic
100% working
Thanks a "fix" not a solution.
Rather silly to have to jump through hoops to make a mobile phone recognise available reception
Have the same problem
I have the same problem now, any solution for that?

Network and GPS Functionality Vanished

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.

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!
