This is why I put a skin on any of my phones before putting it in a case.
I ordered one of those "free" stealth guard skins, despite their reviews, because its cheap and it covers the phone. I'm not gonna put it on 'til Otterbox comes out with their cases, and when I get mine, i'll throw the skin on and then put it in the case. Not concerned with the quality of them (stealth guard) too much especially if its just going to be inside another case. It's more there for the extra protection factor...
I currently don't have anything on the phone at all right now, and have been lucky that there's no scratches or marks *yet* on it...hopefully Obox will get their act together and get the cases out soon, 'cause I can't wait!
