Update: Well, actually, the Lighting to 30-pin adapter does, in fact, carry an audio signal. It also has an analog to digital converter to make that happen. Thanks to the fine journalist Mike Rose at TUAW, we now can put this “controversy” to rest. The ‘iPod Out’ function is actually a feature that lets remote screens in cars or other devices share song info and other graphic displays from the iOS device. If you own a car with this functionality, you’ll still be able to listen to music via the Lightning to 30-Pin adapter, but you won’t get the same graphic display as before.
The source at CNN, below, was incorrect in their assumption, and I erroneously passed that along to you – my apologies.
