I'm a regular user of this forum but I'm unable to find out if I can unlock my Iphone 3GS 3.1.3 with baseband 5.12.01. This is the original OS / baseband when I got my phone from AT&T. And credible pointers / info would be greatly appreciated.
Thanks guys for your answers. One last question: Should I wait for a jailbreak / unlock on ios4 or should I just stay on 3.1.3 and unlock and maybe later upgrade?
Being patient and waiting has rarely let me down. I vote for waiting even though iOS 4 is an amazing upgrade that is bound to test your dedication to Jailbreaking and Unlocking.
