As per the title, I have at least 20 small scratches (0.5-1cm long) on my iPod's screen. I have no idea how they got there as I keep my iPod in my pocket with my wallet and nothing else. My pocket is CLEAN. My the back of my iPod touches the wallet. What else could cause these scratches? Dropping my iPod has never done anything to the screen and it's never been scratched by something you'd think could scratch it, i.e. keys.
