I have the white iPhone 4S and it makes the iPhone look kind of grey with it on. The mirror works, but you can still see the "grey" tint of the phone. I think it'll look better on the black one. However, it does give off a rainbow/3D effect which i did not like. It made me feel cross-eyed. I would only recommend this for the black iPhone 4S and if you don't mind the 3D effect.
