Pair of HTC Windows Phone 7 devices hit the FCC

Not much in the way of specifics here, but a pair of HTC Windows Phone 7 devices have just turned up on the FCC's website, which leads us to believe that some phones might actually be launching any day now. Unfortunately, there's not even so much as a product name to be found (let alone images), but Phone Arena notes that one of the devices uses the WCDMA Band IV, which would make it a likely candidate for T-Mobile, while the other phone's WCDMA V band suggests that it's headed for AT&T.
