Auto-Speaker Phone Via Proximity Sensor?

Hey guys,

I've tried looking around, but haven't yet seen an app or tweak that will automatically turn on the speaker phone, unless the proximity sensor is engaged. Does anyone know if this has been made? Or do any coders want to try and write a program like this?

It only makes sense that if you don't have the phone next to your face to talk, you still want to be on the line with the person. =P

 

CallLock unfortunately has nothing to do with enabling or disabling the speaker phone automatically. Just turns off the screen when your face gets close (though the iPhone should already do this, hah).
