Okay stupid question time... As with any new gadget there are those little plastic protective sheets on the display and camera, etc. that you pull off. I also found one between the display and keyboard halves of the phone. It has a little handle of a tag on one corner so I'm thinking it should come off but I'm not sure. So my stupid question is... should that plastic peel off thing between the phone halves come off or is it there for a reason?
