I have a couple questions about the iPhone and this seems the place to get some answers. Ok I bought my phone of Apple the other day and i was wondering if i can just take my sim card (AT&T) and put it in the iPhone and will it work? Im pretty sure someone told told me u need a special plan to use the iPhone, is that true? If its true that i need a special plan is there anyway to get around it? My buddy hacked his iPhone and he uses it just as a portable WiFi and music player.
