Microsoft is seeking approval from the FCC for a wireless device that was submitted on Monday. Even though the FCC filing makes no reference of the Zune, some believe it to be the Zune phone.  According to Rob Enderle, an analyst with the research firm the Enderle Group, said the filing seems to indicate "an internet device or a mobile VoIP phone," that "certainly could be a Zune derivative product." It’s possible that Microsoft is teaching the Zune a new trick beyond peer-to-peer sharing; like VoIP.

Microsoft says the intended use of the device is "consumer broadband access and networking."Â So unlike the iPhone, it will utilize OFDM, a technology that can be used to route digital TV and voice calls via the Internet.

Going this route allows Microsoft to sidestep partnering with large cellular carriers, who demand a high level of control over product launches.
