Global wireless entertainment publisher JAMDAT Mobile

on Hutch, India's leading cellular service provider. "JAMDAT Bowling,"
"JAMDAT Pool," "Pitfall!" and "Wakeboarding" are available now on
Planet Hutch, Hutch's data services platform.
   "JAMDAT Bowling" is one of the most popular JAMDAT titles of all
time. Players can choose to play a single game or a three game series
and maneuver their aim, power and pin meter for maximum control.
"JAMDAT Pool" is another favorite casual title -- letting mobile
gamers play eight and nine ball on their mobile phones. "Pitfall!" is
the wireless version of the classic title as players guide Pitfall
Harry through more than 200 perilous jungle screens. Lastly,
"Wakeboarding" allows mobile gamers to join Shaun Murray and other top
pros for supercharged wakeboard action.

the leading cellular service providers in that market," said Minard
Hamilton, Executive Vice President of Sales and Marketing of JAMDAT
Mobile Inc. "Hutch's core consumer base is the urban population, which
is the ideal target for JAMDAT's innovative wireless titles. We look
forward to providing JAMDAT's games to the millions of wireless
subscribers throughout India on Hutch's cellular network."
