I have an Phone 4 and a Jawbone icon. When using the Bluetooth with my phone it is garble and will disconnect when I am two or three feet from the phone. The phone and jawbone has been replaced and I still have the same problem. Why
I had a 2nd generation jawbone, and the range on those isn't great with the iPhone4. Not sure why. Range on the iP4 is 30' easy streaming music over bluetooth, and I've used other BT headsets with range of 10' plus - so I would guess it's the jawbone.
