Many have said that the process Apple uses to approve and disapprove apps for its App Store seems arbitrary. When Apple denies apps developers often get nothing more than a cryptic explanation of why the app was denied.

The latest app to get the denial treatment from Apple was the Google voice app. InformationWeek reports that the FCC sent letters Friday to both Apple and AT&T seeking more information on how apps are approved and disapproved.

AT&T says it has no bearing over the approval of apps on the App Store. Apple has said that it disapproves apps that duplicate functionality already available on the device like browsers and music player apps. You would think if Microsoft can’t exclude browsers from its computers that the same would apply to Apple and its smartphones. Perhaps the FCC can get to the bottom of the story.
