In what may be a last-ditch effort at survival, BlackBerry 10 will be introduced today. Research In Motion (RIM) is hoping it will turn around BlackBerry’s decline to 4.6% market share and revitalize the brand. The first two new BlackBerry 10 smartphones are also being introduced. The unveiling will occur at a live webcast beginning at 10 am ET, which can be accessed via http://www1.rim.com/newsroom.html.
