Ok, here is the deal. It's gonna happen. Just go ahead and accept the fact you have a scratch and let it go. I used to baby my Pearl until I got used to dropping it. Now its been dropped on the floor, in a cup of coffee (after 3 months, it dried out and worked fine) in the mud, on my floor mat, etc. It's scratched all to hell, but now I don't worry about it. I guess I'm trying to break it so I can get a new Pearl Flip!
Oh yeah, sorry you scratched your Blackberry.
