Alright, currently I'm on a 3GS unlocked and on T-Mobile, with a jailbreak on it as well. I'm running on iOS 4.2.1 I need some help with the fact that, if I upgrade it to iOS 5, when it comes out, will I be able to unlock it again, so that I can still use it on T-Mobile? I don't mind losing my jailbreak items, I've only got a few apps and themes and a couple of cydgets. I can just re-download those if needed. I guess this is kind of confusing.. If I upgrade my iPhone to iOS 5 when it comes out, will I be able to unlock/jailbreak it again? If you could help me out, I'd appreciate it.
