What part of the phone controls service and reception?
I have an Apple iPhone 3GS. I gave it to a friend to switch the housing and I do not know ehere he went wrong but when i recieved the phone back I could not get even get one bar of service or reach the internet with my SIM card. Everything works perfectly fine on the phone, except the phone and service itself. Screen, speakers, apps, speed all there but no phone calls or internet. Any clue what piece inside the phone would need to be replaced so I could get it to be more than an ipod again?
Is this a good question?
