Apple has been accused of making VoIP unavailable in its iPhone developer SDK due to pressure from AT&T in the past. However, that seems like an unfair accusation now as they have finally updated the iPhone developer SDK to allow for VoIP over 3G network.
VoIP in the iPhone has been a source of controversy after the Google's VoIP was denied access to the iPhone. With the new SDK update, Apple have changed their stand against VoIP as it is now available in its iPhone SDK.
With the latest revisions Apple has made to the iPhone developer agreement and Software Development Kit, VoIP for the iPhone and iPod Touch now enabled unrestricted free local and long distance calling over 3G data networks.
iCall is the first to launch a VoIP app for iPhone after this new SDK development. Hopefully, others like Skype will follow.
