Where is the Unity 3.5 iphone scripting reference located?

I’m using Unity 3.5 and want to read about all the new Unity 3.5 iphone-specific methods and properties, like microphone input. When I look in Unity–>Help–>Scripting Reference, I don’t see any iphone-specific information.

There’s almost nothing in scripting that’s iPhone-specific. Just type “microphone” in the scripting reference search box.
