iTunes 8.1 brought us some snazzy improvements to Party Shuffle iTunes DJ and the iPhone's Remote app. That wasn't the only iPhone-related improvement, however, as Ars Techica notes, there's a new feature that used to be reserved for the iPod Shuffle that you can now use for the iPhone: Autofill.
Autofill essentially lets you just fill up the empty space on your iPhone with some randomly chosen music (you can choose to leave some space open for installing apps and the like later on). As somebody who's not really into constantly creating playlists and managing albums, it's a nice option. A nice option that's squirreled away in a pretty difficult to find place.
