Editors' note: This story was updated to clarify what will be supported by the Lightning to 30-pin Connector Cable.
Out with the old, in with the new...and a new adapter so that the new can still work with the old.
It certainly wasn't a secret that the iPhone 5 was getting a new dock connector. The new Lightning connector is 80 percent smaller. Prior iPhones used an iPod 30-pin connector, which launched in 2003.
Unfortunately, that means any accessories or cables you have that use the 30-pin connector won't fit. However, this 8-inch cable will bridge the gap, letting you connect the old connector to the new Lightning port.
According to Apple's site, the adapter cable will support analog audio output, USB audio, as well as syncing and charging. Video output is not supported, however, and not all 30-pin devices will be supported, either, so you may still need buy new accessories to use with the iPhone 5 and 2012 iPods.
The Apple Lightning to 30-pin Connector Cable will sell for $39. If you don't need the cable, you can pick up a $29 adapter to accomplish the same thing.
