Problem not solved
Speakerphone mode was merely using the phone's microphone as the microphone, not the headphone's microphone. I think. I got a replacement new phone in the mail from Verizon, tried it, and the same problem occurs with the headphone microphone.
I guess Droid 2 users simply aren't supposed to use wired headphones.
