A Zune phone? We’re sure you’ve heard plenty of rumors indicating of such a device, so what’s so special about this one? Well, a new Zune software update that was just released (version 18.104.22.168) seems to be hinting of such a device. Inside the Zune.inf file, code has been found that identifies a “Phone”, along with a vendor ID that is locked to Microsoft, along with 3 different product IDs that could correspond to 3 different phone models. Of course, this could be related to the Zune being integrated into Windows Mobile 7 in the future, but with Mobile World Congress just around the corner, you can’t help but think that Microsoft might spring a surprise on us.
