March 11, 2005

Bellevue, Washington and Waterloo, ON - The days are getting longer, temperatures are getting warmer and thoughts of getting out of the office are getting stronger. Today, with the introduction of the BlackBerry 7290 Wireless Handheld™, T-Mobile USA, Inc. and Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) are making it easier than ever for mobile consumers to get out of the office, balancing work and life, while staying connected.  

Operating on T-Mobile’s GSM/GPRS network, the BlackBerry 7290™ builds upon the proven and popular BlackBerry experience with new features including quad-band and Bluetooth® support, but maintains the same great functionality that consumers have come to expect from BlackBerry, including “always on” access to corporate and personal email, phone, text messaging, browser, organizer, and corporate data applications.

For the international traveler, new quad-band support allows customers to stay connected with wireless voice calls in more than 175 countries*. The Blackberry 7290 also offers integrated Bluetooth® support, allowing for a hands-free option as well as integrated attachment viewing that includes support for popular text and image file formats such as Word, Excel, PowerPoint, WordPerfect, PDF, ASCII, JPEG, GIF, BMP, TIFF and PNG.   In addition, the BlackBerry 7290 from T-Mobile USA maintains excellent battery performance, a convenient full QWERTY keyboard and supports all the new features of BlackBerry Enterprise Server v4.0™.

“At T-Mobile we’re always looking for ways to simplify the lives of mobile professionals who lead an active lifestyle,” said Todd Achilles, Director of Handset Product Management for T-Mobile USA, Inc. “The Blackberry 7290 offers customers an opportunity to live and work how they want from virtually anywhere in the world.”

“T-Mobile USA and RIM share a successful history of providing new and innovative ways for mobile customers to stay in the loop,” said Mark Guibert, Vice President, Corporate Marketing, Research In Motion.  “The BlackBerry 7290 offers powerful functionality with smooth usability for the mobile professional that needs a top-grade business tool to help manage their busy day.”

The BlackBerry 7290 is available today via T-Mobile business sales channels. In mid-April, the company plans to make the device available at T-Mobile retail stores, select national retailers, as well as online at www.t-mobile.com.
