With reports that RIM (makers of the Blackberry and operators of its OS and system) floating the possibility of splitting its hardware business (the Blackberry devices) from its network and messaging business (the OS and messaging network), several big Net/Mobile players have reportedly expressed interest in the various pieces.
According to press reports, Amazon and Facebook are potential suitors, and RIM might approach Apple and Google about helping them get into the networking business. Still, these are rumors, and nothing solid is likely to occur until after RIM launches the BlackBerry 10 operating platform later this year. How this ends will likely depend on whether the new OS is innovative enough for RIM to win back some of the market share its lost over the last few years.
