Viber: Free Phone Calls From The iPhone Over WiFi And 3G [video]

Viber is an iPhone application that lets you make free phone calls to other iPhone users that have Viber installed. When you use Viber, your phone calls to any other Viber user are free, and the sound quality is much better than a regular call.
