JAMDAT Mobile Launches LMA Manager 2006 in Europe; Popular Mobile Gaming Title Returns for the 2006 Season

Global wireless entertainment publisher JAMDAT Mobile
Inc. (NASDAQ:JMDT), under its license agreement with Codemasters, a
leading video game developer and publisher, announced today the launch
of LMA Manager 2006. The title will be available to mobile operators
throughout Europe beginning February 2006.
   LMA Manager 2006, the mobile version of the popular football
management console title, gives mobile gamers the opportunity to act
as a top manager. Revamped for the 2006 season, the game immerses
consumers into the business of football management -- managing teams
and tracking players. In the 2006 edition, users can access new
elements including a revised training feature which tracks players'
training and helps managers control fatigue and injuries. Mobile
gamers can also monitor players' fitness levels, manage success
targets (which will be set by the board at the start of each season)
and use the new finance screen to raise sponsorships and meet wage
demands, as they manage their teams to victory.
   "LMA Manager is an incredibly addictive and popular franchise in
Europe," said Javier Ferreira, Director of Marketing Europe, JAMDAT
Mobile Europe. "LMA Manager 2006 transforms Europeans' favorite
football management game into an exciting made-for-mobile experience."
