Hey, I'm probably not going to stay here long, but I need some help. I have a jailbroken iPod Touch 2nd gen. and the headphone jack has become loose. I was wondering if I could unjailbreak it, and then send it in for repair (I still have the warrenty). I heard that jailbreaking your iPod will void the warrenty. So basically to sum up my question, will Apple be able to detect that my iPod HAS been jailbroken, even after I've unjailbroken it. I really hope this made sense. And I really need some help, thanks!
