LOS ANGELES (GaeaTimes.com) — Apple has updated the iPhone developer SDK to allow VoIP calls over 3G wireless networks, an option that was once only available over a WiFi connection.

iCall’s VoIP application is, according to the release, “the first and only VoIP application that functions on the iPhone and iPod Touch over cellular 3G networks.”

The no-VOIP-over-3G restriction had been in place since the launch of the iPhone SDK due to Apple agreements with AT&T. Back in October, AT&T announced that it would open up its 3G network to VoIP applications on the iPhone, and it appears that Apple is just now taking action.

iCall is a privately held company providing a free and low-cost VoIP calling platform that is currently available for your desktop PC, iPhone and iPod Touch. iCall saves consumers money on phone calling through ad-supported calling. iCall is one of the few VoIP applications that has been permitted by Apple to operate on the iPhone platform.

iCall CEO Arlo Gilbert is quoted as saying,

I applaud Apple’s decision to allow iCall to extend its functionality beyond Wi-Fi and onto the 3G networks. This heralds a new era for VoIP applications on mobile platforms, especially for iCall and our free calling model. I hope that now more developers will begin using our VoIP as a platform to integrate VoIP into their applications.

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.appleipad
