It seems like the most obvious thing we need with the new OS 3.0 is a really simple little bluetooth minijack that will plug into the aux port in car stereos. But I can't seem to find anything that simple! Ideally, it won't even have a mic since the iphone is mounted on the dash quite close the driver. Basically, it will just be a bluetooth headphone with a minijack instead of the headphones! Has anyone seen anything like this? I can't find it anywhere.
