LAS VEGAS--(BUSINESS WIRE)--Oct. 22, 2003

Cingular Wireless and Research In Motion (RIM) (Nasdaq:RIMM) (TSX: RIM) are demonstrating the new BlackBerry 7280(TM) handheld at CTIA Wireless I.T. & Entertainment 2003 in Las Vegas (Cingular booth #821, RIM booth #320). The BlackBerry 7280 is designed to provide the best combined email/data/phone experience and features a high-resolution color screen with added 850 MHz support allowing it to operate in new markets on the Cingular wireless network. It will operate on Cingular's 850/1900 MHz GSM/GPRS network in the United States and supports international roaming on 1800 MHz networks.

The Java-based BlackBerry 7280, the newest wireless handheld to be offered by Cingular, combines phone, email, SMS, organizer, Web and corporate data applications in a single handheld. The new high-resolution screen displays crisp images with support for over 65,000 colors while the handheld continues to offer superior battery life for optimal wireless performance. The BlackBerry 7280 also features cradle-free wireless email synchronization, integrated attachment viewing (including support for popular file formats such as Word, Excel, PowerPoint, WordPerfect, PDF and ASCII) and remote address look up in addition to secure, push-based wireless connectivity.

"Cingular is committed to providing our customers with the best available products and services on our Mobitex and GSM/GPRS networks," said Charles Nelson, President of Cingular Interactive. "The new GPRS-based BlackBerry 7280 will enable us to extend BlackBerry to additional markets by providing customers with a secure, push-based wireless solution on our 850 MHz network."

"BlackBerry continues to be the preferred solution for businesses and government agencies to stay connected and productive," said Don Morrison, Chief Operating Officer at Research In Motion. "We are pleased to expand our long-standing relationship with Cingular to offer a range of BlackBerry handhelds that support all of Cingular's customers and wireless networks."

The new handheld will be available through Cingular as part of the Cingular Xpress Mail(TM) with BlackBerry service. The BlackBerry 7280 works with BlackBerry Enterprise Server(TM) software that supports both Microsoft(R) Exchange and IBM Lotus(R) Domino(TM) environments with single mailbox integration and provides IT departments with centralized administration, end-to-end security (using Triple DES encryption), multi-network support and a powerful development platform. Cingular customers can choose the Xpress Mail with BlackBerry service operating on Cingular's GSM/GPRS or Mobitex networks according to their specific needs. Customers can also easily maintain a mixed deployment supported by a single BlackBerry Enterprise Server.
