There's no way of telling whether this is the rumored Zune phone's interface, but the guys at Mad4Mobiles recently dug up this MS patent that shows what looks like a smartphone interface. The interface has icons for TV, music, weather and shopping. Personally I think it looks a little too cluttered, but if this is indeed the Zune phone interface, it looks like it'll be packed with features.
