Where are the mics located on Nokia lumia 920?

I know there is one on top but that is it when there should be 3.

Beside the MicroUSB ports there is one. Not sure which side but I know both sides are speakers too. IIRC there are only 2 mics on the 920

As far as I can tell from this article: Report - Nokia Lumia 920 sports HAAC Rich Recording microphones | Windows Phone Central it says:

According to SlashGear, the Windows Phone sports a trio of special microphones Nokia co-developed for Rich Recording.

I believe the mic's are in a sort of 'Y' formation, with 1 at the bottom and 2 at the top so that when you point your phone to record video the mics pick up the best sound. I looked into this quite a lot when I was thinking of getting the 920 so I think this is how it is.
