<b>Sydney,  Australia  and  Waterloo,  Canada </b>- Telstra  and  Research  In Motion  (RIM)  (Nasdaq:  RIMM;  TSX:  RIM) have  announced  the
availability of BlackBerry(R)on Telstra's CDMA mobile network in Australia.</font></p>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>&#147;The ability to work or stay in
constant touch while out of the office, virtually anywhere in Australia, has just got
easier,&#148; said Jenny Roche, Head of Small Business and CDMA at Telstra. &#147;Making
BlackBerry available on our CDMA network will enable many more Australians, wherever they
are based, to keep business moving, while they&#146;re moving.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>The CDMA-based BlackBerry 7250&#153;

use with headset or car kit, a bright full color screen, full HTML Web browsing and 32MB
of memory for storing messages, calendar appointments and pictures. This powerful handheld

Telstra is extending the BlackBerry platform to its CDMA customers,&#148; said Mark
Guibert, Vice President, Corporate Marketing at Research In Motion. &#147;Telstra has been
quick to deploy the BlackBerry 7250, enabling more customers in Australia to enjoy the
communications and productivity benefits of the push-based BlackBerry platform.&#148; </FONT></P>
