I've had no problems with the anodized coating on my black/slate model. I put a screen protector and case on it from day one. Today I was cleaning my phone when I noticed a scratch on the glass by the camera. Upon closer inspection, I started to notice approximately 10 more of the same scratches. They are hairline and all vertical. I've never had this issue with my 4 or 4S anyone else notice this? These are both on the top and the bottom portions.
