I have a iphone 5 ios 6.0.2 jailbroken and am thinking of upgrading to the new ios 7. What is the best way to do it with out any leftover. Dont want to end up w a corrupt version but want to have all my settings and apps restored as easily as possible. Have searched and found no real info on how to correctly back up and restore my device from a jailbroken status to the new ios 7
