I was reading about all the line out questions regarding the new dock. Will Smith from tested really should have double checked with Apple before tweeting what he did.
I mean, Apple did make a point of showing an iphone with music playing, with a new dock adapter, connecting to a car.
Of course, anyone who uses a line out connection now knows that Apple removed the volume controls from the UI, since line out is constant 1Vrms anyway. So either this pic implies that Apple changed the UI or they just made a mockup screen, not bothering to remove the volume control element.
Or the iphone is simply charging in the car and the music is playing from the iphone speaker. which would make this image from Apple the most misleading thing from yesterday's announcement.
