Long Zheng found some several lines on the latest zune firmware update that might point out a future Zune Phone. It’s intriguing why a Phone would be included as a component on the update. These text below came from an .INF file extracted from the driver package:
%Phone.DeviceDesc% = ZuneMTPZUSB, USB\VID_045E&PID_0640
%Phone.DeviceDesc% = ZuneMTPZUSB, USB\VID_045E&PID_0641
%Phone.DeviceDesc% = ZuneMTPZUSB, USB\VID_045E&PID_0642
