Research In Motion today released a beta version of its popular BlackBerry Messenger (BBM) service that would enable users to make free voice calls over Wi-Fi with other BBM users. With BBM 7 users can see which contacts are available for a call and can make the call directly from the app. Users will also be able to continue to BBM with the other user while talking to them or chat with others or use other apps at the same time.
One of the other big features of BBM 7 is it will back up the user’s profile, contacts and groups with one BlackBerry ID to enable easy transfer whenever the user shifts to another BlackBerry smartphone. BBM 7 is currently available as a beta and is compatible with BB OS 6 and upwards though RIM says it will bring it to older smartphones running BB OS 5 at a future date. Users can access BBM 7 by signing up for BlackBerry Beta Zone.
