An update to Viber has hit the App Store and the Viber users can be able to send and get the free text messages to one another, including the notifications for incoming text messages. Previously, this VoIP app allows the iPhone users to make free free calls over 3G and WiFi with excellent call quality to other Viber users. No "registration" is necessary. This app is available for Free in iTunes now.
The update also brings a number of UI changes:
# ‘Favorites’ tab has been moved to the top in Contacts tab.
# Improved calling mechanism.
# Deactivation feature.
# Shows the current state of Viber call.
# More Control.
You can download the Updated Viber App (2.01) for iPhone here at iTunes Stores (hit the link) for Free, which is 5MB of size and the device should be running iOS 3.1 or higher.
