Is there a speakerphone switching app?

Is there an app that automatically switches from speakerphone to ear piece based on the proximity detector?

I think it would be useful if there was an app that starts when in phone mode, and detects when the phone is being held to my ear and automatically switches from speaker to ear piece and back as the screen turns off or on based on the proximity detector.

With the more and more frequent state laws on hands free cell phone use while driving, something like this could be quite useful. I, for one would be willing to pay for something like this

Bump!

I'm not sure if an app exists, but it sure is a good idea. I'd pick it up.

Haven't looked into it but I'll bet Tasker could do this (among many other things).

You could use a headset while driving or start the call in speakerphone mode.
