A rumor surfaced recently, saying that Samsung will be licensing RIM's BlackBerry OS 10 (and even buying RIM). It's not a new rumor, there was one just like it last year. Even so, the rumor proved to be believable enough for RIM's shares to rise (a welcome change in direction, as they have slid down to 2009 levels).
Anyway, Samsung killed the rumor with a terse "Samsung Electronics has not considered the acquisition of Research in Motion or licensing BB10".
Even overlooking that BlackBerry OS 10 won't be out until next year, Samsung already has four OSes to work with - Android (whichdominates the market), Windows Phone (which expands quite rapidly), bada OS (which seems to be reaching the end of its shelf life) and Tizen OS (which will probably replace it).
Analysts from Jefferies, who kicked off the "Samsung will license BB10" rumor claim licensing its OS would be a good move for RIM. That may be so, but it's not happening, or at least for now.
