When I got my iP2 I found a source here on the forum for a gel, plastic, silicone cover for the back of the iP2 that protects the back and lets the smart cover work too. I bought the semi-transparent cover so the Apple logo shows.
I should have bought an opaque cover because the one I bought stains and will not clean up. I can not find a black cover to replace the stained one. Can someone direct me to such a cover?
