New Blackberry 8800 leaked on engadget. Similar to BlackBerry Pearl, it comes complete with multimedia capabilities and an expandable memory slot. The trackball will be available too to provide easy scrolling.

The Blackberry 8800 hardly looks like a Blackberry. Thanks to Boy Genius, Engadget's top-secret spy, we're now able to see the 8800 in its full glory. Code-named as the Gamma Ray, it features a trackball, full QWERTY keyboard, WiFi, microSD, all these features and RIM's wholesome goodness. RIM did away with the track wheel on the side in favor of the track ball so that the design of the device is thinner. This is good, there's nothing wrong with thin and sexy. It's still way too early for price and availability - look for the 8800 Q1 of 2007.
