After Apple finally permitted voice data over 3G, a group of South African developers decided to make an application with a difference.
The Telfree iPhone application is also the first and currently the only application in the entire iTunes library that allows you to receive calls even when you are not logged into the Telfree application, using Push Call technology. The app also offers instant messaging and chat on social networks.
The developers offer a flat-rate to fixed-line and mobile phones, while there is no cost for calls between users.
