No service/searching - poor signal on iPhone.
I got my iPhone 4 about two years ago, and got the screen and backglass changed from black to white about six months ago.
I dropped my phone while it was white but the signal started to disappear, but worked again when i restored it in iTunes.
I changed the glass back because i was going on exchange in the United States for a year, but after a while the service didnt work at all. I have tried everything, almost and i still dont know what is wrong with it!
Is it my antenna that is broke or what could it be?
Is this a good question?
