In updating the iPhone SDK, Apple is now accepting apps that allow for VoIP calls over 3G networks. Until this week, that option had only been available through Wi-Fi.

iCall, the maker of the iCall app first noted the SDK change and has updated its app to be "the first and only VoIP application that functions on the iPhone and iPod Touch over cellular 3G networks."

Apple had previously acquiesced to AT&T, prohibiting VoIP over 3G, leaving applications like Skype and iCall to work only over Wi-Fi.

Says iCall CEO Arlo Gilbert: "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."
