BlackBerry OS 5 users have received a significant update to BBM this week with the latest 7.0.1 version featuring BBM Voice. Since the launch of BBM 7 on BlackBerry 6 and 7 this last December, over 50 million free voice calls have been made.
The latest BBM features baked-in multitasking so users can continue to chat or send attachments while they talk. Your friends list clearly shows which friends of your on on Wi-Fi and able to receive a BBM Voice call. BBM Voice also works seemlessly with your existing mics, bluetooth or otherwise.
