Hey everyone, Ive had my iPhone since launch and I'm noticing a lot of hairline scratches on the back black cover. I've been babying it since I got i. Im careful putting it in my pocket and in my car holder but yet I still have scratches on the back. Is there anyway to remove or buff out the scratches? Im getting my invisishield this week and I don't want to install it and see scratches on the back.. Any ideas would be appreciated expcept for replacing the back because I'm not willing to do that. Thanks
