I was (am?) still confused by this. I had assumed all this time that the FCC questions were regarding the approved-then-removed GV Dialer application.

My understanding is that on other platforms, the Google Voice dialer does actually hijack the actual phone application. (see [1] for a testimonial) To do that, you would need to reach into unauthorized API's. Google has done that in the past and gotten away with it. They used the proximity sensor to detect when they were near the user's ear for their search app. In my reading of it, Apple is implying that this is what the Google app does, and seemingly wants you to connect those dots to the other three apps.

If it is the case that they are reaching into unofficial API's, then Apple had every right to deny that application. What I still don't have an answer for is why was GV Dialer approved and later pulled?
