So I know have a pay-as-you-go (prepaid) iphone 3GS with data plan. I did this without a jailbreak or unlocking: I just moved my sim card from my old dumb AT&T phone into the iphone and did an APN change to allow access to the data plan.
Is there a history of AT&T detecting this and causing trouble? Anything special I should do to prevent detection?
