No. The local cellular provider shut down the Bluetooth on everyone's
fancy phones unless they pay extra to get the feature enabled.

I see lots of people with the bluetooth headset (small percentage, but
lots of people). They look like "first adopter" types who would be
more than happy to pay extra for just about anything like that.

Actually, the carrier doesn't disable this feature. They do disable the
one which allows the cellphone to synchronize its phone book with a PC,
upload/download photos sent/received via the phone, etc.

There was a story in the WSJ a few months ago about a guy who bought a
top of the line phone only to find that his carrier disables most of the
bells and whistles (until a fee is paid). Even if the feature doesn't
involve interaction with the carrier's network. 

The Bluetooth headsets are nice, from what I've heard. Particularly if
you have one of those combo phone-PDA gizmos. Try taking notes on the
PDA while holding it up to your ear for a call. Now, try to drive and
balance your latte too.

Of course one of the advantages of using a headset was to move the
phone's transmitter away from one's head. Now making the headset
wireless sorta defeats this advantage. The acceptable long term
exposure limit (according to the FCC) to RF in the cellular/pcs bands
ranges from 1mW to 5mW per square cm.

There's still an advantage since the BT headset transmitter transmits
MUCH less power than the handset does.    So using the BT headset
greatly reduces the amount of EM power impinging on your brain or
other tender head parts.

What's even nicer is having no cell phone, and no pda, and giving your
latte your full attention. I'm a "never adopter."

I'd worry more about some people's heads acting as tuned cavities and
disrupting the cellular signal.
