ok for starters, I have taken apart a few iphone 4's and put them back together with no problems. the one in question, I did everything as usual and afterwards, i put the sim in, it searches and then says no service. If I move somewhere with better reception I will get some bars but not for long. It seems as if the phone isn't getting contact with the antenna. First, I'm wondering if anyone knows what's going on? also, where does the board connect to the antenna? is it through the dock connector?
