LAUNCH THE NEW BLACKBERRY 7105t AND NEW BLACKBERRY INTERNET E-MAIL SERVICE FOR YAHOO! MAIL USERS </FONT></H1>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2><B>Bellevue, Washington and Waterloo,
ON</B> &#150;T-Mobile USA and Research In Motion (RIM) (Nasdaq: RIMM: TSX: RIM) today
announce the availability of the new BlackBerry&reg; 7105t&#153; together with a new
BlackBerry Internet E-mail&#153; service for Yahoo! Mail users. Whether in a meeting or
out on the road, this new BlackBerry device and service offers an unmatched e-mail
experience, providing busy professionals with the freedom to easily manage both corporate
and personal messages, while on the go. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;RIM and T-Mobile have once
again partnered to give consumers an even easier out-of-the-box experience for BlackBerry
users,&#148; said John Clelland, Senior Vice President of Segment Marketing for T-Mobile
USA. &#147;Now with enhanced Yahoo! Mail access, T-Mobile customers will be able to easily
manage their personal and corporate e-mail all from the new BlackBerry 7105t .&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>Yahoo! Mail is the No. 1 e-mail
service in the world.* Through T-Mobile, Yahoo! and BlackBerry &#150; three brands that
customers highly rely on for their communication needs &#150; users will enjoy enhanced
mobile access to their Yahoo! Mail accounts directly on their BlackBerry handset. With
this new service, users will experience real-time delivery of e-mail messages sent to
their Yahoo! Mail accounts, and enhanced wireless synchronization of sent and deleted
items as well as read/unread message status. For example, Yahoo! Mail messages deleted on
a BlackBerry handset can be automatically deleted in the consumers&#146; Yahoo! Mail
account. In addition, users now have the ability to select different &#147;sent from&#148;
addresses when sending a message &#150; providing users with even more flexibility to
manage both corporate and personal e-mail accounts while on the go. This service is now
available for all T-Mobile USA BlackBerry customers. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>&#147;Today&#146;s busy mobile
professionals are always on the go and need a simple way to stay connected throughout the
day. BlackBerry has become the communications tool of choice for mobile professionals that
want greater freedom and flexibility,&#148; said David Castell, Vice President, Retail
Business Unit at Research In Motion. &#147;Working together with T-Mobile and Yahoo!, we
are now making it even easier for customers to communicate by enabling real-time access to
Yahoo! Mail from their BlackBerry handset.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>Yahoo! is the first Internet e-mail
provider to take advantage of the full suite of new integration options available via
BlackBerry Internet Service&#153; to provide real-time, push-based delivery of Yahoo! Mail
to T-Mobile customers. The new BlackBerry Internet E-mail service from T-Mobile is a
component of BlackBerry Internet Service and provides enhanced integration and wireless
synchronization with e-mail accounts, the ability to use multiple &#147;sent from&#148;
addresses and one-click set up to further simplify the out-of-box user experience. For
individuals and smaller businesses, BlackBerry Internet E-mail&#153; allows users to
access up to ten corporate and/or personal e-mail accounts (including Microsoft&reg;
Exchange, IBM&reg; Lotus Domino&#153; and many popular ISP e-mail accounts) from a single
device. </FONT></P>
