Viber is a mobile app that lets users make free phone calls or send free text messages to other Viber users over 3G or WiFi connections. The company offers an iPhone app, and for the past few months a beta version of an Android app has been available. Now Viber is removing the beta label and announcing the launch of Viber 2.0. It’s available as a free download from the Android Market.

The company says it has more than 20 million registered users — but the more interesting number is 12 million. That’s how many people have actively used the service in the last 30 days, with users talking for an average of 11 minutes per day.

Viber’s Android app has a few features you won’t find in the iPhone app, including tight integration with your phone so that you can see your normal phone call logs and messages from within the Viber app. You can also configure your phone to use the Viber dialer to make normal calls over your cellular network. There’s also a pop-up text notification window that allows you to respond to messages without opening the full app.
