I just got an iPhone 4 from Best Buy and it came with iOS 5.1.1. iOS 5 seems to run very well on it and I don't want to upgrade to iOS 6 because updates are pretty much what killed my iPad. What I'm wondering is, if I jailbreak the phone and then restore it later (to un-jailbreak) will iOS6 be installed automatically? It is already downloaded to iTunes and the little notification is telling me that it is ready to update so I'm afraid that as soon as I hit restore it will install itself. Either way, how can I make sure that I backup my phone exactly as it is, so that I can go back to iOS 5 if I need to? I understand why Apple wants to control what the user does but this is a little ridiculous. If I've already made the informed decision not to update, does there really need to be a red notification on my phone that won't go away? It's like they hate their customers sometimes.
