RIM could bring its jealously guarded BlackBerry Messenger service to Android and the iPhone, a potentially significant rumor claimed Thursday. The strategy would involve a "stripped down" version of BBM that would focus on text chat but omit and geolocation and media sharing to still give users an incentive to use a BlackBerry. Pricing was still in flux, BGR heard, but it could either be free or involve either a one-off or subscription fee to avoid creating too much of a strong incentive to leave BlackBerry hardware.
