iPhone 4 SIM temporarily in original iPhone and keep unlimited data?
i'm wanting sell iphone 4 , use original iphone next month or until iphone 5 comes out. have unlimited data , make sure keep it. did last year in between 3gs , 4 (sold current phone, rocked original iphone until 4 came out) no hiccups in unlimited data. however, before at&t introduced data caps , have non clue whether or not have introduced new policies affect me here. can confirm whether or not go far using original iphone next month or , keep unlimited data? did searching , couldn't find recent on topic. found stuff year ago doesn't much. it's worth original iphone jailbroken (if maybe there's tweak or ensure keep unlimited data).
