Those who own both a Sonos system and an iPhone or ipod Touch now have the option of controlling their Sonos system from not only the indeed very jazzy Sonos controller but from their phone as well.
Specializing in making software for the iPhone, Kupuk has done a very nice job of making this a slick interface. The program identifies Sonos zones and lets you control each individually. It doesn’t mirror the Sonos controller but is an interesting addition. The application can be found at the Apple iPhone App Store.
