I've searched a while and I'm pretty sure that once I've upgraded to iOS 6 beta I can't downgrade the baseband as well if I revert back to 5.1.1 right? I need to to overseas so I want to try and unlock my phone. Upgrading iOS 6 beta was probably an oopsie that I shouldn't have done lol
If there is a way to unlock though that would be awesome. I'm currently on an iPhone 4S on AT&T.
