Viber has updated their VoIP app to version 2.1, bringing changes that users have been requesting as well as an all new voice engine that will improve call quality over low bandwidth networks. If you're not familiar with Viber, it's a voice over IP application that lets users make free calls and send texts to each other, on cellular networks or Wifi. It works really well, and is a great way to manage minutes or text allotments from your carrier.
In addition to the new and improved voice engine, the folks at Viber have also added two things users have been requesting -- picture messaging and location sharing. These work just like the standard messaging app we're used to, and really make for a great update. Top it all off with an updated UI, and it's something to have a look at -- grab it after the break, or check the Market for the update.
