It's October 27th which means Sonos is pushing the 3.1 system software out to its distributed home audio systems. With it comes a slightly tweaked, user interface (color icons! heh) for CR200 owners as well Twitter integration for whatever that's worth to ya (don't worry, it's free). Still no sign of the iPod touch / iPhone app but it's expected to pop on iTunes shortly.Filed under: Portable Audio, Software
