I've got one of these (link below) for my Curve that I don't use. Top loading, horizontal on the belt, has the sleeper magnet - but it only has the belt clip - no belt loops. The belt clip doesn't have a hook per se, but it does have a bend in it toward the end that serves the same function as a hook.
Leather Side Pouch
I personally use the BB OEM plastic holster with the swivel clip, with the phone horizontal at about 1 o'clock on my belt.
If you are interested I'll give it to you for the cost of shipping (4$ or so probably.) I only used it for one day while waiting for my holster to arrive.
