Just four-days ago I posted a review of Viber for iOS citing unavailability of an Android version, the good news is the application can now soon be expected on Android platform as an official video of Viber For Android is now posted online.

I was eager to review Viber but waited for an Android version to get released, sadly Viber For Android is nowhere to seen - so here we have the review of currently available Viber For iOS.

Viber the free VOIP application for iOS (Android and Blackberry versions expected soon) allows users to call other Viber users anywhere in world for free using their 3G or Wi-Fi connection, the best part of this must-have utility is the sound quality which is simply "exceptional".

Viber uses your phones address book and is always in-sync with it, highlighting contacts that have Viber so you know you can call them for free. To get started all you need to do is, enter your phone number and the confirmation code received via SMS.
