My black 16gb has several very small cracks, one between the silence toggle and the screen, one running from the camera lens toward the apple logo, one running from the end of the sim slot by the whole toward the apple logo and one near the dock connector, these are not scratches, they actually distort light reflected along them like the case is warped there. I called apple support and while on hold with the support guy I looked up this thread. He said I could get a replacement, but I instead asked if he would make a record of the problem so that I could get a replacement later on when they had fixed the issue. He gave me a case number and said that would not be a problem and was probably a good idea. So call in and get a case number if you are having this issue.
