Disable headphones, leave microphone enabled

[Zinefer]

I have a broken HTC Hero. The built in microphone does not work.

I can get around this problem using the headset jack and plugging in a microphone.

However this routes the sound to the headphones. I have tried modifying ToggleHeadset2...

//setDeviceConnectionState(DEVICE_IN_WIRED_HEADSET, DEVICE_STATE_UNAVAILABLE, "");
setDeviceConnectionState(DEVICE_OUT_WIRED_HEADSET, DEVICE_STATE_UNAVAILABLE, "");
setDeviceConnectionState(DEVICE_OUT_EARPIECE, DEVICE_STATE_AVAILABLE, "");

I thought commenting that line would leave the microphone enabled. This however seems not to be the case.

If anyone could send some code my way that would get this done quick and dirty like I'd be eternally grateful.

Thanks!
