Vodafone and Research In Motion to Deliver BlackBerry™ to Vodafone UK Corporate Customers

Vodafone UK has signed an agreement with wireless solutions manufacturer, Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM), to sell its BlackBerry™ wireless email solution in the UK. BlackBerry is expected to be commercially available to Vodafone's UK corporate customers in June 2002.

Gavin Darby, Chief Operating Officer, Vodafone UK commented: "In today's competitive environment, businesses depend more than ever on email as a fast, effective means of written communication. For the majority, access to email at all times is paramount. The ability to respond to time-critical email communication is seen as a key driver for companies looking to increase productivity and efficiency. RIM's proven track record of success and well-established BlackBerry solution, makes this a natural step for Vodafone."

Operating over Vodafone's GPRS (General Packet Radio Service) network BlackBerry provides business users with an 'always on', seamless and secure link to their corporate email inbox. RIM's unique 'push' technology ensures that emails and calendar appointments are forwarded to the user's BlackBerry Wireless Handheld™ wherever they are. There is no need to dial in or log on.

Following Vodafone's announcement of the introduction of its GPRS roaming capability across 14 European countries, BlackBerry users will be able to maintain their link to their corporate inbox over the Vodafone GPRS network while abroad.

Recent research** in North America discovered that BlackBerry users save around an hour per day because they are able to manage their emails when they are away from their desk or out of the office.

Charles Meyer, Director and Vice President, RIM Europe, said: "We are very pleased to enter into this agreement with Vodafone. Through Vodafone's pan-European roaming arrangements for GPRS and the BlackBerry wireless solution, a UK business traveller will be able to stay in touch with his or her corporate email when visiting the major business centres of Western Europe."

Vodafone plans to initially offer the service with support for Microsoft Exchange with Lotus Domino to follow. Availability may be subject to change according to the Service Provider offering the service. Vodafone UK recommends customers contact their Service Provider for availability.
