I thank you for letting me join.
I have a 2 year-old Droid X, and just purchased
a Plantronics M50 that would not pair.
By reading, I benefited from the experience of another poster
who reported he was able to pair, if he did so immediately
after powering down and up.
It's not in the book, but it permitted me to re-pair
with two bluetooth devices, and use the new one.
I used it for calling today, and no one complained about
the sound quality.
