RIM Introduces New Tri-Band BlackBerry Handheld With Color Screen For Business Users in Europe

O2 UK First to Deliver New BlackBerry 7730™ to Corporate Customers

Waterloo, ON - Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today unveiled the new BlackBerry® 7730 Wireless Handheld™ for mobile professionals in Europe. The BlackBerry 7730™ features a large, bright, color screen, supports worldwide international roaming* on GSM/GPRS networks and delivers email, phone, SMS, browser and organizer applications. The new, Java™-based BlackBerry 7730 is available today for corporate customers in the United Kingdom through O2. Details on pricing and roaming services are available from O2.

"In addition to the phone and email, many of our corporate customers use their BlackBerry handheld to wirelessly access the Internet and a variety of corporate data applications on their company Intranet," said Mike Lazaridis, President and Co-CEO at Research In Motion. "The high-resolution color screen and the large display make the BlackBerry 7730 ideal for business users that need access to corporate applications while out of the office."

Laurence Alexander, Products Director O2 UK said: "We are delighted to offer our customers the latest BlackBerry handheld from RIM. We were the first mobile operator to bring BlackBerry to Europe and it has proved to be a great success. Our relationship with Research In Motion continues to go from strength to strength. This latest announcement is a great example of how we are working together to bring our customers a wide range of data solutions to meet a variety of business needs. The O2 portfolio now includes a range of monochrome and color BlackBerry handhelds at prices to suit all."

Adam Oliver from BT's Chief Information Officer's Team is one of the first customers to trial the new BlackBerry 7730 and is preparing to roll it out within BT. He says: "We currently deploy around 2,500 BlackBerry handhelds across the organization and have always found the benefits to be dramatic. BlackBerry fits in perfectly with BT's ethos, which is to achieve an agile business and a flexible lifestyle."

"The BlackBerry 7730 keeps all the best elements of earlier BlackBerry handhelds, like the superb infrastructure and easy, intuitive interface, but adds exciting new possibilities through the color screen. We are considering new applications enabled by the high resolution color screen, such as mapping and other graphics for engineers in the field, who would normally be reliant on laptops," Oliver continued. "The transition to the BlackBerry 7730 is absolutely painless and the fact that BlackBerry has retained a similar design for the hardware means that training needs are minimal. As ever with BlackBerry, the BlackBerry 7730 allows me to worry about business while BlackBerry worries about connectivity."
