Sometimes FCC filings contain reams of glorious details, but there's very few here -- just the alphanumeric designation for a HTC Windows Phone 7 handset with 802.11 b/g/n WiFi, Bluetooth + EDR, and a set of cellular frequencies (including AWS) that all but peg the phone for a T-Mobile launch. Pay no attention to that "Camera-2nd" listed above, as it's not proof there's a front-facing camera on this device -- rather, the "Sample 2" line indicates that the labs tested a pair of these phones, each with their own photo module. If there does happen to be a second camera on a Windows Phone 7 launch device, however, you'll be the first to know -- we'll be on the lookout for this and other hot new phones at Microsoft's Monday launch.
