Hello, I recently bought a used iPhone 3g and I'm with at&t. I've been "caught" 4-5 times already. Is there a way to prevent them from noticing that I have a iPhone? For financial reasons I cannot pay for the data plan... I heard using SbSettings to shut off 3g and data works but can anyone confirm? Last question, does sending mms(picture, vids, etc) send a red flag to at&t? As in it allows them to know that I have an iPhone? Thank you, happy holidays.
