Hello, I was wondering if anyone could help me - I am currently jailbroken on iPhone 4 iOS 4.1. I have a few things like BiteSMS and SBSettings installed etc, but I am not happy with the speed of the phone just now. I was wondering if there was any way to upgrade to iOS 4.2 and returning to an unjailbroken state without losing all of my data Is the only way to do this to restore as normal and then restore from back up? (i.e. is there a way to do this which will only take a few minutes?) Thanks a lot, Michael.
