My iphone won't slide to unlock. Keeps rebooting. I am running jailbroken 3.0.1...I have sooooooo much stuff on this phone. I can't bring myself to restore it and be stuck with 3.1.....Is there a way to restore it to the 3.0 or 3.01 ipsw I have on my PC? Then rejailbreak it? Agh...It just rebooted again.
