San Antonio, Texas, September 19, 2007

Waterloo, Ontario — Wi-Fi® is coming to AT&T's BlackBerry® handset customers. AT&T Inc. (NYSE:T) and Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) have announced that the first cellular and Wi-Fi BlackBerry handset — the BlackBerry 8820 — will be available beginning Sept. 20 through the nation's largest wireless provider.

AT&T is the leading provider of BlackBerry services worldwide and boasts the broadest domestic and international coverage area for wireless data services of any U.S. carrier.

Customers can also use the BlackBerry 8820 to make or receive wireless phone calls in more than 190 countries.

"The new BlackBerry 8820 builds on AT&T's leading domestic and international coverage footprint by giving customers the ability to link with their company's wireless campus network or access e-mail and browse the Web at Wi-Fi hot spots even in the few countries in which we do not have data roaming agreements," said Jeff Bradley, senior vice president- Marketing and Operations for AT&T's wireless unit. "That makes the BlackBerry 8820 from AT&T an exceptional world phone for global use by business customers and individuals alike."

"The BlackBerry 8820 builds upon the sleek and performance-driven BlackBerry 8800 that has been embraced by business professionals around the world," said Mike Lazaridis, president and co-CEO at RIM. "This powerful new model has been eagerly anticipated by the market, and we are very pleased to be working with AT&T to launch the first cellular and Wi-Fi BlackBerry handset for customers in the U.S."

The BlackBerry 8820 provides support for 802.11a, b and g with enterprise security features, extending the BlackBerry platform to business customers at public hot spots and on wireless local area networks. Customers can use a BlackBerry 8820 to link to their enterprise through home Wi-Fi networks. They also will be able to access broadband services, such as the nation's leading service from AT&T — AT&T Yahoo! High Speed Internet.
