My jailbroken iPod Touch 2G had been playing up, constantly freezing and turning off, but more recently decided not to charge anymore. I decided to restore the iPod via iTunes, but the restore failed, meaning that the iPod only boots up to the Connect to iTunes screen. However, the iPod is not charging even after prolonged periods of charging. I've tried restoring the iPod in DFU mode, but the restore still fails, giving different error messages each time. Also, if I do send the iPod back to Apple under warranty, will there be traces of the jailbreak? Cheers!
