Would it be possible for me to open up an HTC Hero phone, go into the motherboard, and remove the internal microphone...?

Or, if I couldn't remove it... could I at least smash the mic, so it doesn't work..?

If so.... could somebody point out to me where, physically, on the motherboard, the microphone is located, and what it's going to look like....

The reason I ask is, I want to use an external plug-in mic, and I want to get rid of the internal one altogether.

Thanks.
