Are any of the approved VoIP applications allowed to operate on AT&Ts 3G network?
Apple does not know if there is a VoIP element in the way the Google Voice application routes calls and messages, and whether VoIP technology is used over the 3G network by the application. Apple has approved numerous standard VoIP applications (such as Skype, Nimbuzz and iCall) for use over WiFi, but not over AT&T’s 3G network. As we noted in some of our original coverage of the GV controversy, Google Voice is not a VoIP service in the same way that Skype or Gizmo are, since it continues to use the cell network for voice connectivity to the device. Apple’s response to the FCC inquiry shows that they are on the same page. Apple developed a comprehensive review process that looks at every iPhone application that is submitted to Apple. Applications and marketing text are submitted through a web interface. Submitted applications undergo a rigorous review process that tests for vulnerabilities such as software bugs, instability on the iPhone platform, and the use of unauthorized protocols.
