There are four category prizes available;

Each of the category winners above will win a variety of mobile devices.

The overall winner, selected from one of the four category winners and announced at the Wireless and Broadband Forum’s Convergence 2009, will receive a trip to the San Jose “Where 2.0″ conference in May 2009 including flights, accommodation and registration fees.
