Here's Your Chance to Score Big in the AT&T Game Development Contest for Windows Mobile

AT&T Inc. NYSE: T, Microsoft Corp., HTC
Corp. and I-play announced today the creation of the AT&T Game
Development Contest for Windows Mobile to discover the next
breakthrough mobile game. Windows Mobile games represent the
fastest-growing segment of the AT&T gaming business. The AT&T
Game Development Contest, launching May 1, is truly unique as it
represents the first time all members of the mobile gaming ecosystem
are collaborating in an effort to inspire the developer community to
take mobile gaming applications to the next level.

In a May 2007 research report, Gartner Inc. forecast worldwide
mobile gaming end-user revenue to reach $9.6 billion in 2011 -- up
significantly from the $2.9 billion realized in 2006. Gartner
attributes this projected growth in mobile gaming to consumer awareness
and the increase in content being developed by gaming publishers.
AT&T, which has the broadest portfolio of Windows Mobile phones of
any U.S. carrier, currently offers more than 2,300 on-deck mobile games
and is always evaluating innovative and entertaining gaming options to
offer its 71 million-plus mobile customers.

"AT&T has a strong commitment to deliver more wireless choices
to our customers -- in terms of products, services and applications,"
said Mark Collins, vice president, Consumer Data, for AT&T's
wireless unit. "One way we reinforce this commitment and demonstrate
that we are open to innovation is by working closely with the developer
community so that we can bring visibility to their creativity, while
ensuring that our customers have access to the most advanced,
compelling and fun products and services -- now and in the future."

"We are happy to support this contest and encourage developers to
take full advantage of our powerful, flexible platform, providing
AT&T customers with new applications that can enhance their mobile
experiences," said Scott Horn, general manager of the Mobile
Communications Business, Microsoft Corp. "With such a broad portfolio
of AT&T devices, Windows Mobile is ripe for developers looking to
reach a mass audience with their products."

Don Ryan, senior vice president of I-play Publishing, said:
"I-play's integrated support and close collaboration with the mobile
games development community has helped fuel innovation and creativity
since its inception in 1998, and so we are pleased to participate in
such an imaginative relationship. With the recent consolidation of our
publishing division, we can bring a new game to market across many
popular consumer platforms, including Windows Mobile devices. We look
forward to working with the winner and help bring their vision to the
gaming public."

AT&T makes it simple for its millions of customers to discover, shop and play games directly from their phones:

* Look for the menu item called AT&T Mall or the MEdia Mall shopping bag
icon.
* Select Shop Games; you will see a list of categories such as New
Arrivals, Top Sellers and a variety of genres that you can browse to
find the game you want.
* Select a game, then follow the prompts to purchase, download and install
it onto your phone. (Standard data charges apply.)
* Start playing!

Beginning May 1, gaming developers can fill out the online entry
form to submit their Windows Mobile compatible game. All game entries
submitted during the next three months will be reviewed and judged
based on the following criteria: game-play value and quality, game
uniqueness and creativity, and marketplace potential. One grand-prize
winner will receive a mobile game developer contract with I-play, prime
placement of the finished game on the game portal on AT&T MEdia
Mall and a cash prize of $25,000. Prizes will also be awarded to three
finalists and 10 semifinalists. For complete contest details, contest

The deadline to submit an entry is July 31, 2008. The winner will be
announced at CTIA Wireless I.T. & Entertainment 2008 in San
Francisco.
