Business Wire, March 30, 2005

WATERLOO, Ontario & BRUSSELS, Belgium & THE HAGE, The Netherlands -- KPN and Research In Motion (RIM) (Nasdaq:RIMM)(TSX:RIM) have introduced BlackBerry Internet Service(TM) in the Netherlands and in Belgium via BASE, a wholly-owned subsidiary of KPN Mobile N.V. BlackBerry Internet Service provides individual users and smaller businesses with a leading mobile solution for staying connected.

"Adding BlackBerry to our portfolio has been a success and this has been proven by the still growing demand from our enterprise customers," said Marco Visser, Director Sales Corporate Market at KPN Mobile. "Introducing BlackBerry Internet Service for smaller companies and prosumers is a logical next step to fulfil the need for a solution with all the benefits of BlackBerry without having to install the full enterprise solution."

"BASE's introduction of BlackBerry for enterprise customers has been very successful," said Bart Vandesompele, Head of Corporate Communication for BASE. "The timing was right for BlackBerry. After establishing this solution for the corporate market segment, BASE is now looking at customers who don't need the full enterprise solution but still want the benefits of BlackBerry and push email functionality."

BlackBerry(R), developed and manufactured by RIM, helps mobile professionals make the most of their day by enabling them to easily manage their email and other information wherever they are. The BlackBerry Enterprise Solution(TM) is already very popular among KPN and BASE's corporate customers who are also supported by a network of BlackBerry Solutions Partners. With BlackBerry Internet Service, individual users and smaller businesses can now also manage their business and personal email on the go with improved communications and productivity.

"The popularity of BlackBerry continues to grow across Europe and we are pleased to work with KPN to introduce BlackBerry Internet Service to its customers in the Netherlands and Belgium," said Mark Guibert, Vice President, Corporate Marketing at Research In Motion. "Customers will benefit from the flexibility and mobility enabled by BlackBerry with always-on, integrated access to voice and data applications."

BlackBerry Internet Service allows users to access up to ten corporate and/or personal email accounts (including Microsoft(R) Exchange and IBM(R) Lotus(R) Domino(TM) and many popular ISP email accounts) from a single device.

The BlackBerry 'push' architecture enables email to be automatically pushed to the BlackBerry handheld - no dialling in required. Users can also read and forward email attachments (including support for Microsoft Word, Excel, PowerPoint and Acrobat PDF documents).

KPN offers a choice of three BlackBerry Wireless Handhelds(TM) - the BlackBerry 7230(TM), the BlackBerry 7730(TM) and the new BlackBerry 7290(TM). BASE offers a choice of two BlackBerry Wireless Handhelds(TM) - the BlackBerry 7730(TM) and the new BlackBerry 7290(TM). All handhelds combine the capabilities of wireless email, data and phone in one powerful and convenient device. Each BlackBerry handheld also features a clear, high-resolution color screen and an integrated 'QWERTY' keyboard. The BlackBerry 7230 and BlackBerry 7730 handhelds are tri-band (900/1800/1900 MHz), and the BlackBerry 7290 is quad-band (850/900/1800/1900 MHz) to support international roaming. The screen of the BlackBerry 7730(TM) is larger to allow for optimized data viewing capabilities while the BlackBerry 7230(TM) and BlackBerry 7290(TM) are more compact handhelds. The BlackBerry 7290(TM) also includes Bluetooth(R) support, 32 MB memory and a brighter backlight.
