ok so i got an 8gb 3g from a friend yesterday. so today i went and purchased a cheap gophone and activated, tried to throw it in the iphone and all it says is no service. it is jailbroken/unlocked, nothing... i went to the store to see if they could help, they said no, no prepaid.... i called and tried to change over my phone, once i gave the imei number they came back saying it is impossible for prepaid on 3g, ive done this before 6months back for a friend, no go. went back to the att store and they gave me what they said was a "blank" sim that came out of an iphone earlier. tried restoring to 3.0 inserting that sim and unfortunately it didnt even give me the activation screen on itunes to even fail the credit check. simply put, i need help whether it be usin my existin gophone sim (preferably as it has $60 credit on it) or even how to go about gettin this other sim to get to the activation screen. any help will be apreciated, as at this point, i have an expensive itouch.
