T-Mobile and Research In Motion Join Forces to Market the BlackBerry Wireless Email Solution

T-Mobile, the world's largest GSM telecommunications group and Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM), a world leader in the mobile communications market, today agreed that they will work together to market the BlackBerry™ wireless solution to businesses in Europe through T-Mobile's distribution channels.

This new relationship builds on a partnership announced late last year between RIM and VoiceStream (a member of the T-Mobile international group)¹ for the United States and will enable T-Mobile to offer its corporate customers a transatlantic BlackBerry service.

The agreement was signed in Berlin, Germany, in the presence of Canadian Prime Minister, Jean Chrétien and the Lord Mayor of Berlin, Klaus Wowereit.

The partnership involves the marketing of the BlackBerry solution and the development of Java™-based corporate wireless data applications to run on BlackBerry and which can operate over T-Mobile's GPRS (General Packet Radio Service) networks. T-Mobile intends to market the BlackBerry solution in Germany and the wider European market.

The BlackBerry wireless email solution provides business users with an 'always on', seamless and secure link to their corporate email, enabling them to be permanently connected to their corporate inbox. RIM's unique 'push' technology ensures that email is forwarded to the user's BlackBerry Wireless Handheld™ wherever they are. There is no need to dial in to retrieve emails. Recent research² undertaken in North America revealed that BlackBerry users save around an hour per day because they are able to manage their emails from wherever they are.

"This partnership with Research In Motion is a key milestone for T-Mobile's global corporate strategy," said Nikesh Arora, board member of T-Mobile International, New Business and Global Products. "The T-Mobile footprint has taken another step into the corporate market - targeting a new segment while blending best in class infrastructure and technology across two continents."

"Together with our partner Research In Motion, we look forward to bringing the BlackBerry wireless email solution to the German market and later to the wider European market," said Martin Witt, head of the Mobile Business Solutions unit at T-Mobile International. "The solution will enable company employees on the move to utilize unproductive waiting times - using a high-speed, convenient and secure service. This will help to boost productivity. The solution is certainly a worthwhile investment for business enterprises."

Charles Meyer, Director and Vice President, RIM Europe, said: "BlackBerry is a proven, end-to-end solution built on a secure and extensible platform that is ideal for T-Mobile's business customers. We look forward to working with T-Mobile to deliver our unique wireless email solution to the market and also enable additional wireless enterprise applications via our powerful, Java-based architecture."

It is anticipated that BlackBerry will be available in Germany through T-Mobile in summer 2002.
