This summer, RIM is expected to start showing off a number of major changes to its BlackBerry handsets. The goal is to make the businessman's hard working corporate tool an all-around device that will also flourish out of the office and challenge Android, webOS and iOS in multimedia. Toward that end, we have seen clips of a new touchscreen/slider that combines what worked on the Storm with the fantastic typing capabilities of the Bold. As we reported, the BlackBerry 9800 is expected to launch later this year by AT&T, with the latest OS build for RIM, BlackBerry 6. Not only is the UI more intuitive and finger-friendly, it also is expected to offer the new WebKit browser that RIM has been working on. The official video below takes you on a quick tour of the new OS and it looks like RIM has nailed it this time. Combine the new software with a drool producing piece of hardware like the 9800, and it would seem that the Canadian based firm has learned a lot since surviving that torrential Storm more than a year and a half ago.
