After Nokia and T-Mobile told us they'd have something to announce on December 14th, all eyes were on Windows Phone. More specifically, they were on the FCC filing for the Nokia Lumia 710 posted way back in October 21st. WPCentral gave the user manual a read-through only to discover several images like the one you see above, a Nokia Lumia 710 complete with T-Mobile branding. That's as clear a sign as we're likely to get that Nokia is bringing its mid-range Windows Phone to the US first.

It's not entirely surprising as the Lumia 710 is the only Windows Phone device featured on Nokia's US site, but it is a little disappointing for those who were hoping that the flagship Lumia 800 would arrive stateside. Hopefully the Lumia 710 will be available in an array of colors on T-Mobile, because if we were looking to get a straight white Windows Phone on the carrier, the HTC Radar offers some stiff competition.
