I'm buying my sister an iPhone today. iPhone 3G, she wants it on T-Mobile. It's on iOS 4.0.1 with baseband 5.12.04. Does anyone know how to unlock baseband 5.12.04? Google doesn't help because 5.12.04 isn't as common? I used SnowBreeze 2.0.2 and created a jailbroken firmware but have not restored it yet, since I want to know if I can unlock the phone or not. If anyone can help that'd be great thanks!!
