I sure have! And I never expected it! I am 100% careful with my products, I have the invisiblesheild on the back and I knew the front was scratch resistant from videos and the first iPhone. However, my iPhone 3g has many little scratches on the front from normal everyday things, like I think I have put my keys in my pocket with it maybe 5 times, not a good idea. Please tell me others have this problem, if not, take a look at your phone to make sure!
