I've had my white 5 naked since I got it a couple weeks ago (I've had a 5 for a while but I recently got it replaced due to a camera problem). It has 2 small nicks in the chamfer (I have no idea how) and a quarter inch scratch on the screen, though I can only see it when I look at in bright light. Other than that, no dirt or anything it still looks white and shiny.
