The BlackBerry 7780 delivers an exceptional mobile experience thanks to its large, easy-to-read, backlit, 240 x 240 resolution display that supports over 65,000 colours. A backlit QWERTY keyboard designed for incredibly easy thumb-typing adds further convenience. As always with Rogers Wireless, the BlackBerry 7780 features e-mail, phone, SMS, browser and organizer applications.

With the always-on BlackBerry 7780, customers can read, compose, forward, or reply to messages at their convenience and view attachments in common document formats.

“BlackBerry continues to grow in popularity with already more than one million subscribers and we are pleased to work with Rogers Wireless to introduce another choice of handheld for our customers across Canada,” said Mark Guibert, Vice President, Corporate Marketing at Research In Motion. “The new BlackBerry 7780 offers integrated support for both voice and data applications and features a larger, hi-res colour screen that maximizes content viewing for e-mail, intranet, and web applications.”
