Hey guys So I've been wanting to get rid of the jailbreak on my new iPhone 4... even though i'll probably miss 5 icon dock and sb settings ahh ): but regardless, I'm jailbroken on 4.0.1 now obviously... I want to keep my smses and contacts and everything as it is.. how do i back it up so the jailbreak doesn't interfere with the unjailbroken firmware.. so it's clean? One of the slight issues was it was a bit buggy and slightly slower so I don't want that when i restore it... Should i delete everything i've installed from Cydia and then back up - then restore it to whatever firmware? then restore it from back up? Also for the iPhone 3G that I'm passing to my brother, it's currently jailbroken on 3.1.2 i believe I want to restore it so it's completely new but I don't want it on 4.0 as I heard the battery life isn't as good and it's a bit sluggish-er... solution? Thanks in advance!
