<H1 ALIGN=LEFT><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Cingular Wireless Offers
BlackBerry Connect for Palm Treo 650 </FONT></H1>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2><B>Atlanta, Sunnyvale, CA and
Waterloo, ON</B> &#150; Cingular Wireless, Palm, Inc. (Nasdaq: PALM) and Research In
Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today announced availability of BlackBerry&reg;<SUP>
</SUP>Connect&#153; for the Palm&reg;<SUP> </SUP>Treo&#153; 650 smart device. With
BlackBerry Connect software, Cingular customers now can enjoy the feature-rich Treo 650
with the BlackBerry service for a robust and secure solution on the nationwide Cingular
EDGE wireless data network.<SUP>(1)</SUP> </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;The availability of BlackBerry
Connect on the Palm Treo 650 represents a marriage of two very popular wireless offerings
that now gives Cingular customers more choice,&#148; said Michael Woodward, executive
director, mobile professional solutions, for Cingular Wireless. &#147;Businesses can now
leverage their existing BlackBerry Enterprise Server while giving employees a powerful,
new wireless device option.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>BlackBerry Connect for the Treo 650
enables users to benefit from many popular features of the unique &#147;push&#148;-based
BlackBerry architecture via BlackBerry Enterprise Server&#153;. For corporate customers,
BlackBerry Enterprise Server software tightly integrates with Microsoft&reg;<SUP>
</SUP>Exchange and IBM Lotus&reg;<SUP> </SUP>Domino&reg;<SUP> </SUP>and works with
existing enterprise systems to enable secure, push-based wireless access to email and
other corporate data. The Treo 650 operates on Cingular&#146;s EDGE network, the largest
high-speed national wireless data network in the United States with availability in 13,000
cities and towns and along some 40,000 miles of major highways. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>BlackBerry Connect for the Treo 650
supports the following features: </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>
o &nbsp;&nbsp;&nbsp;       "Push" Corporate Email delivers messages automatically -- and wirelessly -- to the Treo 650's inbox. Changes to the inbox,
     including read/unread status and deletion, can be automatically synchronized between the user's email account and the Treo 650.<BR><BR>
o &nbsp;&nbsp;&nbsp;       Wireless Calendar Synchronization keeps the Treo 650's built-in Calendar up to date remotely, allowing users to receive,
     accept or decline meeting requests on the go.<BR><BR>
o  &nbsp;&nbsp;&nbsp;      Attachment Viewing lets users view Excel, Word, PowerPoint, and PDF documents in original format.<SUP>(2)</SUP><BR><BR>
o &nbsp;&nbsp;&nbsp;       Remote Address Lookup (RAL) allows users to search their corporate directory wirelessly for email addresses without the need
     to download every name to the Treo 650.<BR><BR>
o &nbsp;&nbsp;&nbsp;       Enables centralized device management, including support for IT policies such as over-the-air device disablement and
     password device lock, as well as end-to-end security with Triple DES encryption.

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;We are happy to provide another
choice for companies that have deployed BlackBerry Enterprise Server or are planning to do
so,&#148; said Tim Roper, vice president of U.S. region for Palm. &#147;Treo 650 already
is one of the most compelling mobile-computing devices available today for business users,
and the BlackBerry Connect functionality gives Cingular customers another great reason to
adopt Treo as a vital business-productivity tool.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;BlackBerry Connect allows Treo
650 users to tap into the power of the BlackBerry wireless architecture,&#148; said Mark
Guibert, vice president, Corporate Marketing, at Research In Motion. &#147;We see a
growing opportunity for wireless connectivity in the enterprise, and we&#146;re very
pleased to be working with Cingular and Palm to broaden the reach of BlackBerry and to
help customers enhance their mobile communications and productivity.&#148; </FONT></P>
