RIM is apparently planning to extend support for its BlackBerry Messenger (BBM) app cross-platform, with versions for Android and (potentially) Apple’s iOS. According to Boy Genius Report, the strategy and timing of the launch have yet to be determined, but while the app may be free there is the possibility of a subscription fee for use of the service away from BlackBerry devices. It was also suggested that while the apps will enable BBM connectivity for Android and iOS users, it will not include the full feature-set available for BlackBerry device owners – for example image or location sharing may be omitted.

In many ways, the move would seem to make sense for RIM: BBM is essentially a social networking service, and therefore the larger the user base, the better. By limiting the features of BBM on other platforms, it may be hoping to attract new users to the service, who may then be prepared to switch to a BlackBerry device when they upgrade in order to access the additional features.

RIM has previously announced plans to enable third-party developers to integrate apps with BBM, for example to enable customers to exchange messages while playing games. During February 2011, it announced plans for a “gifting” platform integrated with BBM, which will enable users to buy content, apps or other products for other service users. In September 2010, it said it had more than 28 million customers using BBM services.
