LOS ANGELES and SAN FRANCISCO — From the CTIA Wireless I.T. and Entertainment 2004 show at the Moscone Center in San Francisco, global wireless entertainment publisher JAMDAT Mobile Inc. (Nasdaq:JMDT) announced today it has launched Bejeweled Multiplayer, the award-winning gem-matching puzzle game, through Verizon Wireless' Get It Now® downloadable application service.

Recently chosen as "Best Mobile Phone Game" at G-Phoria, "the Award Show 4 Gamers," Bejeweled Multiplayer is a fast-paced wireless game that allows consumers to experience the thrill of exciting head-to-head matches with other players. Bejeweled Multiplayer was adapted and published for wireless by JAMDAT under license from PopCap Games, a leading Seattle-based developer of casual computer games.

Bejeweled Multiplayer's cross-carrier functionality allows players to experience the thrill of competing against subscribers whether their opponent is across town or across the country.

"We are pleased to bring the excitement of Bejeweled Multiplayer to Verizon Wireless' Get It Now customers," said Mitch Lasky, Chairman and CEO of JAMDAT Mobile Inc. "JAMDAT's cross-carrier functionality allows consumers to compete against a greater number of players, enhancing the multiplayer element of the game."

Verizon Wireless Get It Now customers can find Bejeweled Multiplayer in the getGAMES shopping aisle in the Get It Now virtual store that offers customers 500 applications that are easy to use, including games, ringtones, productivity applications and more. Verizon Wireless customers with select Get It Now-enabled phones can purchase Bejeweled Multiplayer for $2.99 monthly access.

Download charges for Get It Now applications vary and airtime charges apply when browsing, downloading and using certain applications. Customers need a Get It Now-enabled handset and Verizon Wireless digital service to access the Get It Now virtual store.
