Ok so I have an iPhone3G that is Jailbroken with 2.2 running 2.2 firmware. My question is how do I go about upgrading to firmware 2.2.1 with jailbreak 2.2.1? I'm currently d/l the 2.2.1 firmware from apple. Do I restore with that firmware and then run the new quickpwn? Will this restore the iPhone from the latest backup?
