I have been searching for this but don't know if I am the only one. Both my friend and myself camped out for the iPhone 4 in Greensboro NC and the whole time Apple was on the news for the antenna and proximity sensor problems we both loved our iPhone4s and had none of the problems that the rest of the country seemed to experience, however, as soon as I updated to the IOS4.0.1 update I have experienced more dropped calls in the same areas that I had no problem talking in before the update and now the Prox sensor is on the fritz making me hang up in the middle of calls and everything else with my cheek. I'm just curious if my friend and I are the only ones that were completely satisfied with my iphone before the update and now I'm just frustrated that I now have the problems that are plaguing the rest of the country.!
