You can buy these at your local Cingular retailer $119. The Silver color only. I bought one yesterday. It pairs fine with my 7100i.

And as in their video demo at www.jawbone.com this baby delivers. I was in a server room with lots of Cisco switches and Dell servers which have noisy fans and this thing canceled all of the noise. I would disable the noise canceling and there was a considerable amount of noise. Turning it back on would eliminate the backround noise. Totally amazing!!! The person I was testing this with was so convinced that he immediately went out to buy one. This product delivers on it's claims.

My next test will be driving in the car and having a conversation with the road noise. Which reminds me of one more thing I like about the jawbone. With the HS850 there were times I couldn't here the caller and would have to press the ear piece up against my ear. Not an issue with the jawbone since the earpiece goes right in the ear.

Some minor cons. I use a moto HS850, which turns on by flipping open the microphone. The jawbone you have to hit a button to turn on and off. Not a big deal, it just became second nature to close the mic and know it was off.

2nd con is my moto has a nice case that goes on my belt when not in use. As of yet there is no case for the jawbone. Both these things are not show stoppers.

If your looking for noise cancellation headset. I would recommend the jawbone without hesitation.
