I really liked Astraware's Casino. Has Texas Holdem and a few more. If you have Sprint, you can get this game for free by going to the powerdeck home page and upgrading your On Demand program to Pocket Express. Pocket Express gives you the option to downloading a cab of this for free
Otherwise, 20 bucks:
