FOR IMMEDIATE RELEASE

Siemens SK65 Mobile Phone Features “BlackBerry Built-In” Technology

RIM’s New “BlackBerry Built-In” Licensing Program Extends BlackBerry Applications and Services to Other Mobile Devices

Waterloo, ON – Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today introduced a new licensing program that allows other device manufacturers to incorporate BlackBerry® software applications in addition to supporting BlackBerry wireless services. Through the BlackBerry Built-In™ licensing program, mobile device manufacturers can incorporate various BlackBerry applications into their own phones or handheld devices including BlackBerry Email™, BlackBerry Calendar™ and BlackBerry Browser™ applications. The Siemens SK65, launched today, is the first mobile phone to feature BlackBerry Built-In™ technology.

Thorsten Heins, President of Mobile Phones within Siemens mobile, commented: “The SK65 is an ingenious all-in-one solution for business professionals that need to stay in control and informed wherever they travel. With a full set of messaging features it means you have more flexibility about where and when you work. Additionally, we have designed the SK65 to offer a contemporary, yet timeless design for professionals who expect outstanding quality in looks and performance.”

Thorsten Heins added: “RIM is a recognized leader of wireless email and wireless enterprise technologies and the BlackBerry wireless platform is ideal for providing push-based email and wireless data services. With RIM’s BlackBerry Built-In™ technology and our innovative design, the SK65 is a breakthrough mobile phone for our customers.”

“The BlackBerry Built-In™ licensing program is another important step that supports RIM’s strategy to provide an open, extensible and scalable wireless platform for a broad range of customers with varying needs and preferences. We invested early and heavily to develop the architecture, applications and infrastructure behind BlackBerry and those efforts can now be leveraged to provide the popular BlackBerry experience to a broader range of devices,” said Jim Balsillie, Chairman and Co-CEO at Research In Motion. “Siemens is a global leader and we are very pleased to work together to enable wireless email, calendar and corporate data access capabilities using BlackBerry Built-In™ technology. Together, Siemens and RIM are providing our customers and partners with a world-class messaging solution and a powerful application environment.”

Through its licensing programs, RIM is adding value for all of its various customers including users, IT departments, developers, carriers and device manufacturers. Users gain a greater choice of devices to satisfy different requirements. IT departments also gain choice and the ability to support multiple device types with a common back-end infrastructure and end-to-end security model. Developers benefit from being able to leverage their applications across multiple devices and channels. Wireless carriers gain from the ability to leverage their success with the BlackBerry platform and address different market segments with a broader selection of devices, operating systems and feature sets. Mobile device manufacturers benefit from the ability to quickly and cost-effectively integrate a proven solution that is deployed by customers and supported by leading carriers worldwide.

The Siemens SK65 is the first mobile phone to feature BlackBerry Built-In™ technology and incorporates BlackBerry Email™, BlackBerry Calendar™ and BlackBerry Browser™ applications. Users get a full BlackBerry experience on a stylish Siemens business phone, including push-based wireless connectivity. The Siemens SK65 will be able to connect to BlackBerry services via both BlackBerry Enterprise Server™ and BlackBerry Web Client™.

For individuals and smaller businesses, BlackBerry Web Client provides an Internet-based email interface that allows users to access multiple existing corporate and/or personal email accounts (including Microsoft® Exchange, IBM Lotus® Domino™ and popular ISP email accounts) from a single device.

For corporate customers, BlackBerry Enterprise Server software tightly integrates with Microsoft Exchange or IBM Lotus Domino (Novell GroupWise support is expected later this year) and works with existing enterprise systems to enable secure, push-based, wireless access to email and other corporate data.

Additionally, the Siemens SK65 supports the Mobile Data Service feature of BlackBerry Enterprise Server, allowing access to corporate data applications on the intranet beyond email. As a leading example, Siemens and RIM are working with SAP to extend SAP Solutions for Mobile Business applications, such as Customer Relationship Management (CRM), to the Siemens SK65 and further increase business efficiency for customers.

The Siemens SK65 with BlackBerry Built-In™ technology is expected to be available in November 2004.
