Iphone 3gs displaying NO SERVICE

i have a iphone 3gs and recently damaged the lcd and digitizer so had them replaced..not through apple. when i picked up the phone all was in good working order. by the time i got home the phone was saying NO SERVICE. and hasnt picked up any since?? ive tried loads of trouble shooting techniques i.e turning airplane mode on n off...removing sim whilst doing this...completley restoring the phone through itunes...updadting software...reseting all and network setting on the phone itself. i have also turned phone off then back on and it will search for networks then 'waiting for activation' is displayed. i really am at a loss as how to fix this problem!! can anyone please help?? (network-orange)

I would take it back to the place that repaired it and have them address the issue. They may not have connected everything properly.

Iphone 3gs displaying no service message

I replaced my old iphone 3gs by a new iphone 4s. After 2 weeks the new iphone was stolen but, when i tried to go back to my old iphone 3gs (with a new sim card), it kept displaying a "no service" message after I updated it to ios 5.1. I got back all the information stored in iCloud and iTunes and all the applications work fine, except for the telephone service. I tried changing different sim cards (including different telephone lines) but the problem remains. The phone worked perfectly well before this incident started. Help!

I forgot to say that I tried restoring the device many times, but couldnt fix it. Any ideas? Searching the apple site,
I saw an article explaining something about "udating carrier settings" http://support.apple.com/kb/TS4148
I dont have such option in my general settings

Iphone 3gs displays no service and cannot activate

I cannot afford a smartphone, so my friend has given me his old iPhone 3GS when he upgraded to a newer model.
the phone has obviously been wiped so that it's as if it just came out the factory.
I enter the language, WiFi network info, etc. have also tried multiple WiFi hotspots, including my home Netgear/AOL, parents Huawei/TalkTalk and a pub's technicolor/plusnet.
whenever i try to activate it, the top bar says "Searching..." and then eventually "no service", and i get a message saying the activation server is unavailable, and have tried again and again to no avail. have tried powering off, removing and re-inserting the SIM, then powering up - same errors. the SIM pins appear all present and not broken/bent etc when I look into the device.
All I can say about the make/model is that it's an iPhone A1303, so it's a 3GS (Identify your iPhone model - Apple Support) . 16GB capacity.
I have no way of knowing the iOS version, IMEI or baseband revision (unless there's a mac/iTunes way of getting it?)
my friend is certain that he has never jailbroken the device, and that it has always been on O2 (the same network as me).
my SIM works in my old Nokia, receives texts/calls etc. my Nokia gets all 4 bars of signal.
I have also been in to visit an O2 shop, and had my tariff upgraded to one for a smartphone. They're certain it's not an O2 problem. I've probably had this SIM at least 8 years.
Have tried activating it by itself, and via iTunes 10.6.3(25) on Mac 10.6.8. iTunes says there is no SIM installed.
is the phone somehow blocked? how would i find out if it was? is it possible that it has been hacked to support O2 instead of another network (by a shop) - and that by scrubbing the data, it has wiped out the hack (in which case, how do i get the phone's ios/baseband/IMEI/original network)? is this a really silly thing like having to deactivate my old phone or having to register the iPhone with O2? is this a problem with the SIM, the phone hardware, the firmware or iOS? what if i got his old SIM - would that activate the phone, and is the phone just not accepting a different SIM than the original one?

Here's what you do
1.Make sure your phone is not plugged into the computer.
2. Put the iPhone into recovery mode (this is NOT DFU mode). Do this by
     a). Hold down both the power/sleep button and the home button until the screen turns black/off
     b). As soon as this happens release the power button but NOT the home button
     c). If done correctly then the Apple logo will appear, KEEP HOLDING THE HOME BUTTON and eventually a connect to itunes graphic will appear. You can release the home button
3. With the connect to itunes graphic on the screen, plug your phone into the computer. iTunes will start up if it is not already on, and then will say the phone needs restoring. Ignore this and COMPLETELY quit iTunes.
4. With iTunes off and the graphic still on the phone screen, hold down both the power/sleep and the home button again for 9 seconds (count 100, 200, 300...) or until the screen goes black
5. When the screen goes black release the home button straight away.
6. It will start up with the iPhone activation screen ignore this. iTunes should have started up, if not do so. Go to the iPhone tab and either resotre from backup or set up as a new phone.

My iPhone 3GS displayed a message that it was overheated, now it wont turn on except for the Apple logo, and iTunes doesn't recognize it!

My iPhone 3GS displayed a message saying it was over heating and to turn it off.
I turned it off and the next day that I turned it back on, it wont go passed the main Apple screen.
It had a message to re-connect to iTunes, then that the IMEI and SIM were unknown.
Now it wont turn on at all!!

The terms of service of the Apple Support Communities prevent us from helping anyone with a jailbroken phone.
You're on your own. Good luck.

IPhone 3GS display connector?

Hi guys i have big problem with iPhone 3GS display,so i need your help here,i was changing battery on my device and the when i wanted to put back display i saw that connector 1 is hard to put on on connector on motherboard so i saw that conncetor one don't havetwo pins ,i know that i need new cable or new display can you please tell me can just replacew another ribbon cable because my LCD display is not broken,if you didm't understad this is the problem,so can i do anything or i need to buy new LCD display.

Your question is a little difficult for me to understand. If you think the LCD Display connector on the Ribbon Cable #1 is damaged, the fix is to purchase a new LCD Display. The Ribbon itself is not truly a replaceable part that I know of.
When working on an iPhone 3GS the iPhone must be OFF, or you risk damaging the LCD Display or the Logic Board components that control the LCD Display.
I do not understand how you know “don’t have two pins”? I have never heard of this problem? If you really know that two pins are out, then also examine the #1 connector on the Logic Board to be certain is has not sustained damage too.

My IPhone 3GS Display is backwards all my writing is backwards way around so are my apps (Like a mirror image)

Hi Hope sombody can help me please..
My IPhone 3GS Display is backwards all my writing is backwards way around so are my apps
(It's like a mirror image) When I put my phone near a mirror everything is displayed fine.
I now have to leave my phone on all the time cos if I press my top button it will display backwards again and then I after keep pressing it loads of times. I have got the latest updates and I have re-booted my phone from scratch I'm running out of ideas. I have phoned Apple up and they have just told me to press my home button down with the other one to re-start it. No Joys :-(
This phone is not jailbroken,I'm on 02 pay as you go it was bought from new 2 years ago from the 02 shop.

Sounds like it's dying. Bring your phone into Apple for an out of warranty exchange for $149 or find a 3rd party repair shop near you.

What do you do if your iphone 3gs displays a tether picture to itunes and won't change? After going throught the manual i came up with a error message1002

What do you do if your iphone 3gs displays a thether picture to itunes? It won't change and after going to the manual and following directions, I find it is an error 1002. What does this mean?

Error 1002, 1011, 1012, 1014: These errors may indicate a hardware issue with your device. Follow the steps in this article. Also attempt to restore while connected with a known-good 30-pin Dock Connector cable, computer, and network to isolate this issue to the device. The MAC address being missing or the IMEI being the default value (00 499901 064000 0) can also confirm a hardware issue.

Faulty iPhone 3GS Display

I recently replaced my cracked iphone 3GS display (with a full front panel assembly) and it worked perfectky for a while, but then the display went and all I can see is the backlight. It goes on when I press the home or lock button and goes off when i repeat. I have tried putting the original panel back (the display still worked on it) and the same problem occured. Please help

There was probably some damage to the logic board that occurred when you cracked the screen. It has gotten much worse.

TS4148 iPhone 4S displays 'No Service' or 'No SIM Card Installed' with iOS 5.1.1 (9B206).

iPhone 4S displays 'No Service' or 'No SIM Card Installed' with iOS 5.1.1 (9B206).
I have just started getting theihs issue the last couple of days where I am having the turn my phone off and on about 4 to 5 times a day. I have looked on the available posts and seen that this is a known issue on iOS 5.0.0 but was fixed for iOS 5.0.1. I have got iOS 5.1.1 (9B206).
Is anyone else having this issue or knows how to fix?

i used to get that , but i simply took out the sim card , dusted it and the sim tray and put it back in , and now i dont get it
maybe the sim isnt positioned correctly , just my two cents
hope this fixes it for you

My iphone 3gs is showing "no service" tried everything please help!!!

If doing a reset (hold the sleep/wake and home button until the Apple logo appears) doesn't correct it then try getting a new SIM from your carrier.
