If you're a fan of the NCAA basketball tournament, you'll want to take a look at this app. PocketBracket ($1.99) lets youcreate brackets, organize pools, and follow the NCAA men's basketball tournament with game and score updates. In addition, you can compete among thousands of users on the PocketBracket Network as well as your friends and coworkers. PocketBracket comes preloaded with 2009 tournament data so you can test-drive the application before the 2010 tournament. You can create sample brackets and begin organizing your pools. Once 2010 data is available on Selection Sunday, PocketBracket will automatically update and remove your sample brackets and your pools will be ready for the 2010 tournament. New features this year include a new user interface and landscape bracket viewing.
