Firstly, my iPod is NOT jailbroken. Everytime I open the music player, it plays the song I select, then when it finishes plays the next song for 5 seconds, then the iPod crashes to the home screen. I can then easily open up music again and play another song, but it gets tedious having to put the wong on every 3-4 minutes. Has anyone ever had this before? And/or got any tips on fixing it?
Was about to suggest the same thing. If you hold the top button and the home screen button simultaneously, you will do a basic restore of your iPod. If you want to do a full restoration of your iPod you will have to connect it to the main computer with a USB cord. Then go into your iTunes and restore the iPod.
A full restore is likely the answer to your problems and if not, it's likely a technical issue with the iPod and you will need to take it to Apple.
