The home button on our iPhone 4 is failing. It only works temperamentally. The iPhone is jailbroken and running iOS 5.0.1. Cydia has all the the SHSH blobs for iOS 4.3.2, 4.3.3, 5.0.1 (& 5.1 which I don't understand as it's never run 5.1). If, after performing my daily backup, I restore to factory settings and return the iPhone to Apple under warranty, I will probably be given a replacement iPhone 4 running iOS 5.1 (which can't yet be jailbroken untethered). Will I be able to restore to 5.0.1 and then restore all my apps / data / jailbreak or will this fail because (as far as I am aware) the SHSH blobs will only help me restore my old phone?
