FOR IMMEDIATE RELEASE

Sony Ericsson and RIM announce BlackBerry connectivity support in P900
smartphone

3GSM World Congress, Cannes, France - Sony Ericsson Mobile Communications and
Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today announced their plans
to enable BlackBerry(R) connectivity on Sony Ericsson mobile phones. The first
product to feature BlackBerry services later this year will be the P900
Symbian OS smartphone.

Sony Ericsson and RIM recently signed an agreement to enable Sony Ericsson's
Symbian OS based phones to connect to BlackBerry Enterprise Server(TM) and
BlackBerry Web Client(TM) services for enterprises and individual users. The
BlackBerry services infrastructure and platform has been approved and deployed
by operators around the world and thousands of companies and government
organisations have already installed BlackBerry Enterprise Server behind their
firewall.

The combination of RIM's 'always on' connectivity and push technology that
automatically delivers emails and other data to and from a wireless device,
makes BlackBerry an efficient and reliable communications platform. The
BlackBerry services will be able to run on the P900, while maintaining the
existing P900 experience and functionality. BlackBerry connectivity support on
the P900 is expected later this year.

"We're delighted to be adding BlackBerry connectivity to the palette of
solutions we support with our smartphones, thereby further expanding customer
choice. The P900 smartphone is a multi-faceted device which offers
productivity, entertainment and communications and our agreement with RIM
ensures our customers a proven, market-leading mobile e-mail and data
solution," says Jan Wareby, Executive Vice President and Head of Sales and
Marketing of Sony Ericsson.

"We are pleased to be working with Sony Ericsson to provide our end-user
customers and carrier partners with greater wireless device choices while
enabling IT departments to leverage their existing BlackBerry infrastructure,"
said Don Morrison, Chief Operating Officer at Research In Motion.

"IT departments and consumers are recognizing the productivity benefits that
can be gained from wireless access to corporate data and email," said Marit
Doving, Executive Vice President, Marketing, Symbian. "RIM has enabled Sony
Ericsson to further exploit the rich functionality of Symbian OS and has now
added integrated, push-based access to email and enterprise information
enabled by RIM's BlackBerry solution."

The BlackBerry architecture for enterprise customers includes back-end
integration with corporate information systems, enhanced manageability and
end-to-end security. BlackBerry for individual users enables push-based access
to one or multiple internet-based email accounts without the need for a
corporate IT platform.

                                    -more-

The P900 is a high-quality communications tool for voice calls, text and
picture messaging and e-mail, as well as providing full PDA/organizer
functions. In addition, it is a camera-phone capable of recording video and
still images and also provides a good gaming experience on the 65K colour
touch-screen. The wide range of applications available for download enables
the P900 to do much more than making voice calls, thereby increasing its value
for both consumers and operators. The P900 is based on Symbian OS v7.0 and the
established UIQ user interface.
