Yea I'm in the same spot, I live in New Jersey which also has a complete ban on cell phone use in the car. It can be ticketed as a primary offense too, meaning that the officer can pull you over for no other reason than you were on your cell phone.
I had the iPhone Bluetooth and while I liked it and thought it was comfortable, the sound quality was crap and most people complained they couldn't hear me very well. I loved it though because it was so small and I could wear it without noticing. But then I dropped it in some coffee and it stopped workin, DOH!
So I think I am going to be picking up the Jawbone 2. It is a lot smaller than the original and I hear the sound quality is awesome for a BT headset. I may head out today to grab one, so if I do I'll let you know what i think.
