first off i live in the USA. i recently got a iphone 3gs n idk if its safe to use. i got it for a ipod touch2g n $20, i restored it jailbroke it 3 times(cuz i kept doing it wrong) than restored it again cuz the jailbrake was untethered. So im asking would i be able to use it? i made calls on it by putting my girls at&t chip in it but the kid i got it from had it for t-mobile which now makes me think i was stolen before but idk the kid a good kid in school but who knows out. am i screwed with a nice lookin ipod or can i use it as a phone?
