The Sonos Controller [iTunes link] recently released an update for iPhone 3.0 and is available on the App Store. This app works seamlessly with the online music services including Deezer, Last.fm, Napster, Pandora, Rhapsody and Sirius.

The free upgrade brings all of the features of the Sonos CR200 Multiroom Music System Controller to the iPhone controller for the Sonos BU250 Multiroom Music System. One of these features includes the “Info View” command. This new feature (accessed using the “i” button on the Now Playing screen) allows you to discover even more music via the various music services available on Sonos.
