About to head over to Best Buy and, assuming they have everything, which is the best case right now? What I'm looking for: Slim design. Covers all sides/top/bottom + back. Preferably one piece but I'll consider two. Nothing that would make it hard to slide in and out of a pocket. Color isn't a huge deal. Aslong as there is a black/grey/white/dark red option I'll be fine. Advice? I can also manage to go to an AT&T store. Neither stores have been answering the phone all day, though, so I'm just gonna go in.
