SDK Changes Open Door to VOIP Over 3G Networks... iPad Phone Calls Possible?
iCall announced today that Apple had made changes to iPhone SDK that makes Voice over IP (VOIP) over cellular networks possible.
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 claims to be one of the few VoIP applications that has been permitted by Apple to operate on the iPhone platform. This allows users to make telephone calls over AT&T's 3G data network without using their plan's minutes.
