I have a factory unlocked GSM iPhone 4S. My dad has my old iPhone 4, locked to AT&T. Both are currently jailbroken. My dad is going abroad later this week, and he needs an unlocked phone. I was just in the process of backing everything up on both phones, planning to then wipe and rejailbreak them, and restore them with each other's settings (using AppBackup and PkgBackup). But it just occurred to me - there's no 4S jailbreak for 5.1, and iirc the SHSH blobs don't work for restoring to 5.0.1. So if I reset my 4S, I'll be stuck without a jailbreak until an A5 5.1 jailbreak comes out, right? Do my dad and I have any recourse, other than paying AT&T an early termination fee and getting them to officially unlock the iPhone 4?
