Hi,
Iphone 3G, iOS 3.1.2, baseband 5.14.02.
I know this baseband is unlockable at the moment with iOS 4.2. How do I unlock on 3.1.2? It was jailbroken, I used ultrasn0w to unlock but doesn't work.
Thank you for your help.

It's a tricky process now because your baseband is 5.14.02. Take a look at the iPhone Dev Blog --> blog.iphone-dev.org
