Speakerphone activate on Face-down for HTC DIAMOND/PRO

Using Gyrator (download here):

- Add a new “Rotation” event.
- Set application to Phone on the “Application” tab.
- On the “Orientation” tab check on “Portrait”, “Face-down”, and “Face-up”.
- On the “Actions” tab check on “Simulate Keypress”.
- Goto “Advanced” tab and select key “F16,127″ which triggers the windows-native “Speakerphone Toggle event”.

Done.

Now, starting NOT on speakerphone, whenever you put your phone on a level surface –facing up or down– during a call, the speakerphone will toggle ON -> Moreover, if you pick it up it should toggle OFF.
