I was having Compass Interference problems and took my Sprint iPhone 4S to an Apple store. They did a complete restore of my iPhone and told me not to revert back to a stored backup. My apps are all out of place now. Can I fix them now and they'll carry over to iOS 6 or would it be best to do a full install with it? I just don't want to waste time fixing it all and syncing music and photos if I'm going to have to do it all again in a week.
