So I just noticed a very, very small spot on the side matte/plastic finish of the white iPhone 4 and I tried my best cleaning it but it isn't going. It looks blackish like dirt, is it possible it scratched? I don't get how it could happen, I haven't taken it anywhere and just bought it 2 days ago. The spot is black/gray and is very very small there isn't a chance I could have scratched it as perfectly as that! Anyone else with similar problem??
