So I got a black 16 GB iPhone 3GS off craigslist and I don't believe that it has ever been jailbroken. I am on ATT so I don't need it to be unlocked. Would I be able to Jailbreak it by using snowbreeze since I don't need it unlocked? I am on software 3.1.3 and modem firmware 5.12.01. Any help on this would be greatly appreciated. Thanks and hope to hear from you soon. Take Care.
