Rogers AT&T Wireless Introduces The BlackBerry 6210 In Canada

Toronto, ON and Waterloo, ON - Rogers™ AT&T® Wireless and Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) today announced the commercial availability of the compact BlackBerry 6210 Wireless Handheld™ in Canada. This handheld has a smaller design than previous GSM/GPRS-based BlackBerry® models, increased memory for greater application and data storage, and new support for wireless e-mail synchronization and integrated attachment viewing but is priced to attract an even greater share of the mass market audience. The BlackBerry 6210™ operates on the industry-leading Rogers AT&T Wireless GSM/GPRS network in Canada with support for international roaming*.

While the BlackBerry 6210’s blue coloured cover certainly stands apart from the traditional black cover, customers will be happy to hear that it still delivers the same popular BlackBerry experience with support for wireless e-mail, phone, SMS, browser and organizer applications, all in a sleek, lightweight, Java-based device.

“Rogers AT&T Wireless has worked closely with Research In Motion and been the first wireless carrier to launch each of RIM’s great new wireless devices in Canada for our GSM/GPRS and Mobitex networks,” said Rob Bruce, Executive Vice President and Chief Marketing Officer, Rogers AT&T Wireless. “The new blue cover, compact design and competitive price of the BlackBerry 6210 is sure to appeal to an even wider audience than previous integrated wireless voice and data devices. The new handheld device is available in Canada only from Rogers AT&T Wireless and adds further power to the line up of BlackBerry applications with the integrated attachment viewer and wireless e-mail synchronization feature.”

“Rogers and RIM continue to offer world-class connectivity solutions and I expect the BlackBerry 6210 to be another extremely popular choice with Canadian customers,” said Mark Guibert, Vice President of Corporate Marketing at Research In Motion. “With integrated support for ‘push-based’ email, a built-in GSM phone, a browser for the wireless Internet, a connected organizer and an open standards based platform, the BlackBerry 6210 gives mobile professionals a distinct advantage in today’s fast-paced society.”

The BlackBerry 6210 costs $449.00 CDN with a two-year service agreement from Rogers AT&T Wireless and is available for purchase across Canada through Rogers AT&T Wireless dealer and retail points of sale, or online at www.rogers.com. Rogers AT&T Wireless offers the widest selection of BlackBerry handhelds in North America, including the BlackBerry 6710 which also operates on the Rogers AT&T Wireless GSM/GPRS network, and the BlackBerry 950 and BlackBerry 957 handhelds, which operate on the Rogers AT&T Wireless Mobitex network.
