We’re not sure if someone just oopsed in the original specs, or if Apple listened to the uproar and made adjustments to the hardware, but the product page has been changed to reflect the fact you will be able to get audio via its new Lightning adapter. As a story at TUAW points out, the “iPod out” feature originally referred to in the specs, which isn’t supported by the adapter, is only for a little used control feature, mostly implemented in high end automobiles (and if you can afford a Beemer, you can probably afford a new Lightning-compatible stereo if you’re upgrading your iPhone).
The text of the product page now reads: “This adapter lets you connect devices with a Lightning connector to many of your 30-pin accessories.* Support for analog audio output, USB audio, as well as syncing and charging. Video output not supported.”
So good news is that the adapter isn’t useless. The bad news is that it’s still probably cheaper to purchase a new clock radio than to buy one of their adapters.
