What about this company for an "invisible shield" are they good? anyone have one? I like the fact that it goes completely around the phone. Motorola Droid INVISIBLE FULL BODY / SCREEN PROTECTOR - eBay (item 170405039780 end time Nov-16-09 13:39:34 PST) Or what about 3M protective coating. Like the stuff used for cars? I guess the adhesive for that would ruin the phone huh?
