Not quite sure that some of this adds up. The leaker works in the iPhone Development Department, yet "no one in the office" can figure out why the phone signals back to Apple when a Facetime session is started? The leaker doesn't have access to the source code? Or doesn't know who would have implemented such a feature? Or is this person simply not a developer?
