IT &amp; Entertainment </B>&#150; Cingular Wireless and Research In Motion (RIM) (Nasdaq:
RIMM; TSX: RIM) today introduced BlackBerry Connect&#153; to the U.S. marketplace.
Cingular is the first U.S. carrier to offer the popular BlackBerry&reg; wireless services
on a third-party handset via the BlackBerry Connect licensing program from RIM. The Nokia
9300 is scheduled to be available in the U.S. through Cingular Wireless beginning in
November. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>Corporate customers can choose the
Nokia 9300 business device as an option to use with the behind-the-firewall BlackBerry
Enterprise Server&#153;, and individual and small business customers can use the Nokia
9300 with BlackBerry Connect to access popular Internet Service Provider (ISP) e-mail
accounts through BlackBerry Internet Service&#153;. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>The Cingular-enabled Nokia 9300
business device with BlackBerry Connect is designed for the mobile professional seeking a
high-quality combination of PDA, phone and mobile email in a sleek, compact device. From a
traditional handset on the outside, opening to a full keyboard on the inside for fast,
efficient text and data input, the Nokia 9300 device offers a compelling voice and data
experience. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->

convergence of two eagerly anticipated, business-focused wireless products &#150; the
Nokia 9300 and BlackBerry Connect &#150; with Cingular&#146;s nationwide* EDGE network,
the largest and fastest national wireless data network in the U.S.,&#148; said Kent Mathy,
president, Business Markets Group, Cingular&#146;s B2B organization. &#147;By bringing all
of these together, Cingular is offering a truly powerful tool and complete voice and data
solution both to businesses and individual users.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;BlackBerry Connect is an
important part of our global strategy to expand the reach of BlackBerry services and
provide customers with a broader choice of handsets while maintaining the important
benefits of the BlackBerry architecture, infrastructure and security model,&#148; said
Mike Lazaridis, president and co-CEO at Research In Motion. &#147;Together with Cingular
and Nokia, we are providing customers with another powerful business solution that
addresses the needs of both users and IT departments.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->

popular, push-based BlackBerry services initially on the Nokia 9300 for those users who
want to access their e-mail and prefer the look, feel and features of the Nokia phone. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->

administrators also can take advantage of the BlackBerry Enterprise Server security
features such as remote deletion of messaging data should a device be lost or stolen.
Through BlackBerry Internet Service, individuals and small business customers can use the
Nokia 9300 with BlackBerry Connect to receive e-mail automatically from up to 10 ISP
e-mail accounts, including popular services such as AOL, Yahoo! and Comcast. Customers can
choose to use the corporate solution or the individual solution, or both at the same time. </FONT></P>
