Can you update your iPod if it's jailbroken?
my sister has a (janky) iPod touch 4th generation and she jailbroke it half a year ago. and when the new iOS 6.1.3 came out she tried updating it but it said "an error has occurred". does she have to unjailbroke it if she wants to update it or not? and how do you unjailbrake it?
