Question about 3.5mm Headphones w/mic

[Habitat]

If I had a pair of iphone 3g headphones that come with the mic, and i hooked it up to the g1 with the micro usb to stereo adapter, would the microphone work?

I asked the same question, but did not yet get a full answer:

The adapters are female and therefore you cannot easily see if there are four contacts or just 3. Also, the product descriptions do not answer the question.
