Today Research In Motion (RIM) released their second official video preview of BlackBerry 6, RIM’s newest operating system for BlackBerry smartphones. Slated for release late this summer BB 6 boast a wide range of changes and added features that will likely make a highly favorable impression on those of us who have been long time BlackBerry users as well as attracting new customers to the BB platform. BB 6 looks to bring many enhancements to the overall BlackBerry user experience, with the most notable being; a completely redesigned home screen, a universal search function, context sensitive pop-up menus, built in social and RSS feeds, and best of all the new WebKit powered browser which looks to be a huge leap forward. Still no official word on which current BlackBerry devices will see an upgrade to OS 6, but we’ll keep you posted. Check out video above and feel free to leave a comment, and let us know what you think about the new OS 6.
