Hi
im guessing by this time all of you know that if you are a At&t customer (not sure about other carriers) that even if you have unlocked iphone and you put your sim in it,they automatically have you online that your using iphone,BUT when i have called At&t people couple of times,they don't seem to know that i have iphone.So just to make sure At&t don't know i have iphone 100%,is there a way to block THAT THING that tells At&t im using iphone????
