The Apple Universal Dock serves as a convenient and elegant home base for charging, syncing, and more. Through the use of interchangeable inserts called Dock Adapters, it works with iPhone and all iPod models that have a dock connector. So even if you own more than one iPod or iPhone, you can keep just one Dock connected to your computer, stereo, or TV.
