I currently have a jail broken iPhone 4 running 4.0.1 and is very stable. I want enable the new FaceTime capabilities that 4.1 brings, but not sure how to update my phone to 4.1 (not 4.2) and get my phone jail broken again. I do not need to unlock, just jailbreak. Cn someone guide me to how to do this? I have been reading all over the place on what the easiest way to do this is, but would like a straight answer. Help!
