MUNICH, Germany & WATERLOO, Ontario--(BUSINESS WIRE)--April 2, 2004

Siemens mobile, the mobile arm of Siemens AG, and Research In Motion (RIM) (Nasdaq:RIMM) (TSX:RIM) today announced plans to enable BlackBerry(R) connectivity on Siemens mobile phones. Siemens and RIM will work together to provide integrated data connectivity capabilities on Siemens mobile phones using BlackBerry email, calendar and browser applications. Siemens plans to introduce a BlackBerry-enabled handset based on its own 65 platform for mobile phones in the fourth quarter of 2004.

RIM's BlackBerry Connect(TM) licensing program will help Siemens enable its wireless phones to connect to email and corporate data applications via BlackBerry Enterprise Server(TM) using the same secure, push-based wireless architecture and infrastructure that currently supports thousands of companies and government organizations around the world. The companies also intend to work together to enable Siemens mobile phones to connect to BlackBerry Web Client(TM) services for individuals and smaller businesses.

"We look forward to working with RIM to integrate the BlackBerry experience with our mobile phones," said Thorsten Heins, President of Mobile Phones within the Information and Communication Mobile group (Siemens mobile). "Our customers want simplicity, power and style all in one device and the unique push-based BlackBerry services will provide users with always-on access to important information."

"We are pleased to work with Siemens to offer BlackBerry email, calendar and browser applications on Siemens mobile phones," said Don Morrison, Chief Operating Officer at Research In Motion. "BlackBerry connectivity on Siemens mobile phones will enable users to stay connected with email and other data applications and allow IT departments and carriers to leverage their existing investments in the BlackBerry platform."

Siemens plans to introduce a BlackBerry-enabled handset based on its 65 platform for mobile phones in the fourth quarter of 2004. The 65 platform is Siemens' latest platform for mobile phones. The company recently has introduced a variety of phones based on this powerful platform for rich multimedia messaging including digital video and photo capabilities.
