There are lots of great VOIP applications out there for the iPhone, such as iCall which allows you to make free calls to the United States and Canada, Skype and Fring. What was one of the main disadvantages of these applications is that we were unable to use them over our 3G connection, thus only permitting us to make calls over WiFi.
Apple along with AT&T have decided to ban VOIP over 3G connection, thus removing the capability from the iPhone SDK, that only allowed developers to use WiFi connection. However back in October, AT&T announced that it would start allowing VOIP applications on the iPhone to use 3G connectivity, but not until now that Apple has made this possible.
Before this, we used to have an application known as “3G Unrestrictor“, which is a utility that allowed VOIP over 3G. This utility have not always worked, and if caught using it, it may cause you some legal troubles.
However, iCall have issued a press release on Wednesday stating that Apple has permitted VOIP over 3G connections, thus upgrading the iPhone’s SDK.
With the latest revisions Apple has made to the iPhone developer agreement and Software Development Kit, iCall for the iPhone and iPod Touch now enabled unrestricted free local and long distance calling over 3G data networks. iCall with support for VoIP over 3G networks is now available in the App Store for download. iCall is the first and only VoIP application available for the iPhone platform that allows use over 3G networks. iCall for the iPhone and iPod Touch may now be downloaded from the App Store at http://itunes.apple.com/us/app/icall-free-voip/id293837001?mt=8&uo=6
This is a major step by Apple and AT&T in which they permitted the usage of VOPI applications over 3G, which would definitely help decrease our phone bills and make our iPhones more interesting.
