I was looking into buying a new iPhone 3GS, but I would need to unlock and jailbreak it, does anybody know if i order a 3GS online from AT&T does it come with 3.0 or 3.1? because that would be imperative because from my understanding there is noway to unlock a 3GS on 3.1 if it came with 3.1 and i have a windows computer not a mac so a custom pwn wouldnt be possible..
