GMGruman writes: Hewlett-Packard is planning to unveil its Palm WebOS strategy in a few weeks, while RIM is allegedly working up a new version of its popular Curve that uses the new BlackBerry OS 6 and its touch interface. WebOS has largely faded from view since HP bought it nine months ago, and RIM's been largely silent since its summer release of the BlackBerry Torch, its first successful modern BlackBerry, and the fall announcement of its PlayBook tablet. Meanwhile, it's been an Apple iOS and Google Android show at CES 2011, in the popular press, and in customers' hands. (Microsoft and Nokia essentially ceased to matter by Christmas 2010.) Is it too late for WebOS and BlackBerry? InfoWorld's Galen Gruman suggests they're running out of time and that the public signs of their plans are not so positive. Still, the two "also-ran" mobile OSes have a couple opportunities to resurrect themselves, he suggests.
