Does anyone know were i can buy a rear protector for ipad2 whats like a fine film, similar to the screen ones on the front. 1 with camera hole, speaker cut out/round ect. Just looked on Amazon uk and verious other sites and theres none. I keep it in a case but would like to protect the back even whilst its in the case/cover for when i take it out.. U.K sites pref. if possible. Thanks.
