Apple updated the iPhone software development kit on Wednesday to allow internet telephony apps to work on the 3G network. The little-noticed move effectively unlocks the ability for the iPhone — and the upcoming iPad — to be used as web phones.
ICall, a voice-over-Internet Protocol (VOIP) calling company, said the latest revisions in Apple’s iPhone developer agreement and software development kit enable the iPhone to make phone calls over 3G data networks. ICall promptly released an update to its app today, adding the 3G support.
Because the iPad includes a microphone and will run iPhone apps, that means the tablet will gain internet telephony, too.
