I called a local atnt store a few hours ago and was told that the jawbone doesnt work with iphone. :-\
lol, well not too shocking that they would tell you that... haha

I was in a ATT store the other day and the clerk asked me how I was liking my iPhone so far. Told him it was cool, but was really looking forward to the first software update and am hoping they add some new features... He responded: "Oh yeah, thinner and lighter is always better!"...
It *does* work with the iPhone and very well... pairing was extremely easy compared to the Moto brand BT headset I once tried with my old RAZR.
I've had the black jawbone for about 2 weeks now... when I first started using it, took me forever to get the thing on and off my ear everytime, but after some practice, it's very easy.
Sound quality is great and very comfortable to wear. As others have said, callers say there's no difference in sound quality, they can't tell I'm using a BT headset. Only thing I don't like is, the on/off button is a bit difficult to press while you're wearing the headset.
And here's something interesting that I learned...
I was getting some static when wearing it at home, a friend told me that my wifi network was probably causing the interference. So I tried it in the car, away from any wifi - and wow, was crystal clear, no static or crackling.
