HTC HD2 multi-touch zooming shown in GPS Navigation app

We have had HTC HD2 videos in Bulgarian, Greek, German, Portuguese, Polish, very occasionally English and now Arabic also.

The above video review shows the HD2 being its usual speedy self, but also shows one feature not often shown off – multi-touch in applications that are not designed for it.

In the above video, around the 5th minute, we see the reviewer zooming the iGo GPS Navigation map using multi-touch, with a small pop-up screen helping the user know where in the app he is currently.  It is unlikely the app needed any adaptation at all to make this work. Of course without such adaptation the utility is limited to simply enlarging onscreen content, but presumably HTC also has a hidden API which would allow apps to use this feature more intelligently.
