My iPod Touch 3G (32GB) has slightly raised bezel (or slightly sunken glass) and I thought it is no big deal when I bought it in September. But, it's bugging me more and more as the time goes. I bought it from Costco so I still can return it within 3 months of purchase. However, I'd feel bad returning it for a full refund after using it for more than 2 months. Should I just keep it?
