alright so i finally talked to a AT&T guy and told me to switch the sim card out of my old iPhone into new iPhone. so i did that and now it works. now i was very happy but now, i notice something else. maybe this is just all 3g iPhones but in te contacts, it freezes up aot. like it takes more time to hit a contact, then hit the number, it freezes and is very slow. has this happen to anyone else?
