I have one of the "pouch" cases from thepouch.com. Mine has the long flap and belt loop. Protects the N810 very well, but the case is pretty big... probably a half-inch wider and longer than the nokia. Also, the company didn't put a card holder in my pouch, despite what the website claimed. If they won't replace it, I'll sew one in myself, though.

I'm quite a far on the material the "pouches" are made out of. I'll try to post some pictures later when I'm at my regular computer.
