FOR IMMEDIATE RELEASE

LOS ANGELES and LONDON - (January 19, 2006) - Global wireless entertainment publisher JAMDAT Mobile Inc. (NASDAQ: JMDT), under its license agreement with Sony Computer Entertainment America, announced today that SOCOM: U.S. Navy SEALs Mobile Recon will be available to mobile operators in Austria, France, Germany, Greece, Ireland, Italy, Portugal, Spain, Switzerland and the United Kingdom. The title, a real-time strategy game full of team-based action and cinematic gameplay, will launch across Europe beginning February 2006.

SOCOM: U.S. Navy SEALs Mobile Recon allows mobile gamers to command a two-man Navy SEAL recon team by assigning orders, shooting, sniping and blasting their way through eight intense missions. Players fight enemies with multiple assault rifles, C4 explosives and knives as they make their way through moving vehicles and power lines, machine gun turrets, flying birds, swaying trees and explosives. SOCOM: U.S. Navy SEALs Mobile Recon allows mobile thrill seekers the ability to relive the SOCOM experience, anytime, anywhere.

"SOCOM: U.S. Navy SEALs Mobile Recon transforms the popular and familiar SOCOM world into an exciting made-for-mobile experience," said Minard Hamilton, Executive Vice President of Sales and Marketing of JAMDAT Mobile Inc. "The title has been a runaway success in North America and, through our European launch, we will be able to reach a tremendous group of both wireless gamers and SOCOM fans throughout Europe."

SOCOM: U.S. Navy SEALs Mobile Recon has already received rave reviews from influential gaming Web sites, including:

GameDAILY (rated 4 out of 5)

"Jamdat is the leader in making quality software for these platforms and SOCOM U.S. Navy SEALs Mobile Recon is yet another shining example of how this company outperforms the competition. The fine attention to detail as well as the commitment to creating an enjoyable gameplay experience (and following through on both of those points) has become the publisher's pedigree for success and I hope a deal is struck with Sony to produce a sequel."

IGN Wireless (rated 9 out of 10)

"Like JAMDAT's DOOM RPG, SOCOM: US Navy SEALs Mobile Recon feels more like a video game that you just happen to play on a cellphone rather than a video game you can just tell was crammed on to a handset. Don't miss this one."

SOCOM: U.S. Navy SEALs and SOCOM II: U.S. Navy SEALs set the standard for online console gaming

tactical team-based gaming, selling over six million units on the PlayStation 2 platform to date, making the

franchise among the best-selling squad-based war strategy titles of all time. SOCOM II: U.S. Navy SEALs

broke online console penetration records within the first two days of its release. Other SOCOM titles

include SOCOM 3: U.S. Navy SEALs, the third title in the popular, squad-based war strategy game

franchise, and SOCOM: U.S. Navy SEALs FireTeam Bravo, the franchise's first title for the award winning

PSP^TM (PlayStation^® Portable) system.
