Is there a nice Droid case that will "lock" the slide feature? I'm thinking a single piece that would go around the entire phone, essentially keeping the screen from ever sliding open as long as the case is on it. I never use the keyboard and the phone randomly slides open all the time in my pocket and for some reason the phone goes crazy when the screen is slid halfway open. I thought I saw something in this section of the site a few weeks ago but now I can't find it. Thanks!
