AT&T, Cingular Wireless and Yahoo! Launch AT&T Yahoo! Go Mobile

Integrated Service Gives Users Real-Time Access to AT&T Yahoo! ® Portal, Communications Services and Customized Content

San Antonio, Texas, February 21, 2006, AT&T Inc. (NYSE: T), Cingular Wireless® and Yahoo! Inc. (Nasdaq: YHOO) today announced the availability of AT&T Yahoo! Go Mobile, the first-of-its-kind integrated service that gives consumers real-time access to their favorite AT&T Yahoo! Internet customized online content, services and community on a wireless phone.

AT&T is now offering the AT&T Yahoo! Go Mobile service on the Nokia 6682 handset from Cingular within the AT&T traditional 13-state service area. The service will also be available in certain Cingular stores in the Austin, Columbus and Los Angeles markets. The service was initially announced at the Consumer Electronics Show (CES) in early January and is only now available for consumers to purchase pre-loaded on handsets.

The AT&T Yahoo! Go Mobile service is the first time that AT&T Yahoo! Internet subscribers will be able to seamlessly access, in a single mobile application, a comprehensive set of their personalized AT&T Yahoo! services, including Mail, Photos, Address Book, Calendar, Messenger and Web, Image and Local search, as well as customized news, weather and sports.

The AT&T Yahoo! communications services are also connected to the built-in e-mail, messaging, address book and calendar applications on the mobile phone, giving consumers one reliable source for the information they find most vital. For example, if a user loses his mobile device, his saved contact information will still be available to him on the Web and easily synched with a new mobile device.

For AT&T, this new application supports an initiative by the company to integrate AT&T services and content across the three screens that many consumers value most today: the PC, the cell phone and the TV. For Yahoo!, this new service is part of a suite of innovative applications designed to extend the reach of Yahoo!’s services beyond the browser.

“We’re helping our customers enjoy the digital lifestyle by giving them virtually anywhere, anytime access to their already personalized and customized Web-based communications and entertainment services,” said Scott Helbing, chief marketing officer, AT&T Consumer. “We’re blurring the lines between the PC and the wireless phone so that consumers can stay in touch, check e-mail, get updates on news and weather — minute to minute, day by day — regardless of where they are or what screen they are watching.”

“Consumers want to connect to their favorite Web services on their mobile devices, and AT&T Yahoo! Go Mobile makes it easy,” said Marco Boerries, senior vice president, Connected Life, Yahoo!. “We have created a service unmatched in the mobile marketplace and are excited to give consumers a single way to simply connect to all of their information and content while on the go.”

AT&T is selling the cutting-edge Nokia 6682 handset through its sales channels for $199.99 after a $50 Nokia mail-in rebate (does not include sales tax and shipping costs) with a new two-year Cingular service plan. The AT&T Yahoo! Go Mobile application is pre-loaded on the handsets at no additional cost. Cingular’s standard wireless data usage charges apply, and Cingular Wireless voice service and data plans are sold separately.

In addition to the integration capabilities of the AT&T Yahoo! Go Mobile service, the Nokia 6682 handset is loaded with advanced hardware features, such as an internal MP3 player, data storage with removable media and a digital voice recorder.
