LOS ANGELES and BEDMINSTER, NJ – February 1,
2005 – Global wireless entertainment publisher JAMDAT Mobile Inc. (NASDAQ: JMDT)
and Verizon Wireless, the nation’s leading wireless provider, announced today
the availability of "JAMDAT 3D Bowling" on V CAST, the nation’s first true 3G
wireless broadband consumer multimedia service. V CAST enables customers to view
crystal clear graphics for 3D games and short content because it runs on Verizon
Wireless’ Evolution-Data Optimized (EV-DO) network – the only widely available
wide-area wireless broadband network in the United States. The V CAST coverage
area, which mirrors the Verizon Wireless EV-DO network, is available in more
than 30 major metropolitan markets and covers more than 75 million people.

"JAMDAT 3D Bowling" allows players to
transform their mobile phones into virtual bowling alleys, with new,
state-of-the-art 3D graphics. The high-tech graphics engine enables gamers to
see straight down the lane and change camera views while they bowl. With the new
wide selection of lanes, balls and pin colors and multiplayer options, "JAMDAT
3D Bowling" is the most complete bowling experience outside the neighborhood
bowling alley.

"’JAMDAT 3D Bowling’ takes one of the most
popular video games to a whole new level with an incredible 3D gameplay
experience on V CAST from Verizon Wireless," said Mitch Lasky, Chairman and CEO
of JAMDAT Mobile Inc. "JAMDAT continues to be at the forefront of gameplay
innovation and third-generation multimedia services are the next step in
wireless entertainment."

Bowling," in the getGAMES aisle. V CAST also gives customers unlimited airtime

For $15.00 monthly access added to their
