According to some BGR sources, RIM is reportedly to bring it’s exclusive messenger service to other platforms like Android and iOS.
RIM has not yet finalized details surrounding timing or pricing, but we have heard that the company might make the software free to all users. We’re also told strategy is still being developed, however, and RIM may end up charging users a one-time fee or even a recurring fee for access to its BBM service on third-party platforms.
Although BBM may come to other platforms, RIM plans to release only a stripped down version of the messenger and users will still need to be using a Blackberry device to enjoy the full fledge services and features.
RIM chose Android first because of the fact that it could develop and integrate something like this much easier with an open platform, but the plan is to build and deploy an iOS version at some point as well.
