AT&T Offers New Sony Ericsson W760a Walkman(TM) Mobile Phone

New 3G Walkman(TM) Phone Delivers Unique Entertainment Experience on Nation’s Fastest 3G Network

DALLAS and RESEARCH TRIANGLE PARK, N.C., Oct. 13 — Shake, rattle and rock ‘n’ roll! AT&T Inc. (NYSE: T) and Sony Ericsson
today announced the availability of the Sony Ericsson W760a Walkman(TM)
phone — the first 3G Walkman(TM) phone in the U.S. The W760a delivers one
of the most well-rounded, on-the-go entertainment and music experiences
today and features an accelerometer that gives customers the ability to
interact with the device for enhanced music and gaming.

The integrated accelerometer allows customers to shake or tilt the
W760a to fast-forward to the next song or to simulate motion while playing
video games. Dedicated A and B gaming buttons also allow customers extra
control and interactivity, making this a truly great device for gaming
enthusiasts.

“Why use buttons when motion can guide mobile entertainment?” said
Carlton Hill, vice president of Devices and Product Development for AT&T’s
wireless operations. “Whether using the W760a to play a bowling game by
mimicking the action or simply shaking it to listen to the next song in
your playlist, the W760a can follow your lead.”

Joining the popular W580 and recently launched W350 Sony Ericsson
Walkman(TM) phones at AT&T, the W760a phone integrates the Walkman(TM)
music player with the full suite of AT&T Mobile Music applications,
including Napster Mobile, eMusic Mobile, Music ID and XM Radio.

“We’re excited to offer a full portfolio of Walkman(TM) devices at a
variety of price points for a broad range of users and are excited about
the continued growth of our relationship with AT&T,” said Najmi Jarwala,
president of Sony Ericsson North America. “With the availability of the
W760a Walkman(TM) phone, U.S. consumers now have a full range of
Walkman(TM) devices to choose from that fit their budget, their style and
meet their desire for mobile phones that provide a robust entertainment
experience.”

The W760a has a long list of features including Mobile Email, instant
messenger, full HTML Web browsing, a 3.2 megapixel camera and AT&T
Navigator for turn-by-turn directions and mapping functions. New W760a
customers can demo AT&T Navigator with a 30-day free trial(1).

The W760a will be available for $129.99 after a two-year agreement and
mail-in-rebate(2) and comes in red, black and silver, with silver exclusive
to RadioShack for a limited time. Consumers can roam the globe in more than
200 countries and still stay connected thanks to the W760a Walkman(TM)
phone’s 3G mobile broadband speeds that make it quick and easy to download
media, share pictures and surf the Internet on the nation’s fastest 3G
