I have a diamond case I bought from best buy on launch day I believe it's from ifrogz and I took it off today to clean my phone and on the back of my ip4 there are a million impressions from where the diamonds cross! My micro fiber cloth won't take them off, any suggestions? I don't want to replace my phone, it has no other problems I'll take a pic of the case from my ip4, I can't take a pic of my iPhone till I get my camera charged tomorrow
