BBM beta for Android gets Channels and voice chat

Android users who've enjoyed their first taste of BBM will want to visit the BlackBerry Beta Zone today. BlackBerry has just released a private beta of the messaging client that introduces promised Channels and Voice support, giving Android users the same social feeds and free WiFi calling as their BB10 bretheren. There's no mention of when the feature will reach either the public BBM build or its iOS equivalent, but it's clear that wider availability is close at hand.
