AIPW Summary: This application relates to the iPod’s user interface, the multiple screens involved, and navigating through those screens. Claim 1 recites a multi-level UI, each level including a list that is related to a list on another level. Also of note is that dependent claim 2, independent claim 3, and Figure 6 all describe the UI in connection with a cell phone. However, the phone-based interface shown in Figure 6 utilizes keys, and is nothing like the iPhone interface.
