My computer wasnt recognising my iPod it so I sent it out to get repaired, and when I got my ordinary box back in, it had a brand nwe iPod in plastic. I started to resent my old one because the case I had scratched it, but now that I have a new one, I can start over. What case should I get so the screen and especially the back wont scratch? Its a 3rd gen 10 gb iPod.
