Apple has updated the iPhone developer SDK to allow VoIP over cellular networks. iCall is the first and only VoIP application that functions on the iPhone and iPod Touch over cellular 3G networks.

iCall is a market leader in desktop and mobile-based desktop calling platforms, including its highly popular version for the Apple iPhone. Until today, restrictions imposed on developers prohibited VoIP functionality on any 3G network.

VoIP on the iPhone has been the source of many debates with companies such as Google being denied access to the platform and the FCC inquiring as to the restrictions in the Apple App Store; iCall is one of the few VoIP applications that has been permitted by Apple to operate on the iPhone platform.

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

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."
