I can't look on the back of my iPhone 3G anymore! It has a lot of scratches, maybe they aren't deep and you can't see them by first look but if you put iPhone under light you will see them, so my question is: Will InvisibleShield hide scratches on back of my iPhone 3G? And if I have it will this Shield make Multi-Touch worse, I mean will it be less sensitive than Multi-Touch without shield?
