Following up on last week's announcement of AT&T's mobile NCAA March Madness coverage, we can now tell you that mobile platform provider Crisp Wireless is powering the portal and giving it all sorts of bells and whistles.

In addition to the usual scores, statistics and bracket updates, subscribers with 3G phones will have access to video highlights as well.

Crisp is also the muscle behind the AT&T Bracket Challenge, which lets AT&T mobile customers create, track and manage their tournament bracket entirely on their phone. Challenge participants will also compete against each other for a chance to win prizes, including the grand prize of a cool $10,000.
