I have this iPod with me, the most lovely little music player ever. When I looked at it's back, a mysterious dent appeared. A major one. It's big, but not big enough to damage the internal components. It looks hideous. Disgusting. Horrible. I need the back replaced. I got the white version, and I've always wanted to get the blue one so I guess that's possible too with the replacement (right?). So, is it possible to have the back replaced (not the whole thing, just the back). How much would the repair be?
