&#150; Orlando, FL &#150;</B> Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today
introduced the BlackBerry&reg; Mobile Voice System (BlackBerry&reg; MVS), the first

the BlackBerry&reg; Device Software, BlackBerry&reg; Enterprise Server and Ascendent&reg;

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>With a new intuitive menu interface,
BlackBerry smartphone users can place, receive and manage enterprise calls from their
handset with ease. The user&#146;s corporate identity (caller ID) is extended to the
handset and allows users to give out one &#147;Reach Me Anywhere&#148; phone number that
simultaneously rings their desk phone and BlackBerry smartphone. Mobile users are also
able to access desk phone functions such as transfer, park, and extension dialing directly
from the BlackBerry phone menu. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>BlackBerry MVS also leverages the
standard security features, IT policies and system management functionality provided
within the BlackBerry Enterprise Solution, extending the administrative tools and services
of the BlackBerry platform to the Ascendent Voice Mobility Suite. Among key security
benefits is the ability to automatically authenticate mobile users to the PBX to help
ensure that only authorized users and devices are accessing the corporate telephony
system. Further, since calls are routed through the corporate PBX, any calls placed from a
BlackBerry smartphone can now be logged or recorded for compliance with applicable
corporate and regulatory requirements. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;RIM&#146;s ability to deliver a

ability to now deliver the same value proposition for both voice and data systems provides
