Blackberry promised us BBM 2.0 early 2014 and it looks like they are delivering. The update is expected to be available on the Google Play store and the Apple itunes AppStore today. It wasn't available when I checked but they confirmed it is coming.

What does BBM 2.0 bring?

• BBM Voice : is a cross-platform VOIP system
• BBM Channels : is a twitter like BBM only one-to-many messaging system
• BBM Location: location sharing now available via Glympse
• Attachments: Ability to attach voice notes, calendar events and contacts to a BMM message
• Dropbox integration for file sharing

So keep checking your app store.
