Viber, the cross-platform VoIP app popular for its free voice calling and text messaging, has received its official upgrade for Ice Cream Sandwich-compatability, available now in the Android Market. Viber arrived on Android last summer and just recently announced that it has reached a 50 million registered users milestone. Viber uses your 3G/4G or WiFi connection to call or text other registered Android or iOS Viber users for free.
In addition to support for Android 4.0, the most recent update also brings with it "significant enhancements" to the Viber voice engine, promising better voice quality, improved support for lower-end devices, and better handling of poor network quality. Other recent updates have brought location and photo sharing, as well as UI improvements, including the ability to see when another person is typing a text message.
If you've got a Galaxy Nexus or a shiny new ICS ROM on one of your devices, you'll want to grab the update from the Android Market after the break.
