It's one of the most barebones filings we've seen in recent memory, but there's no mistaking that at least one Windows Phone 7 device from HTC is going to make a stateside debut. If we had to guess, we'd say that this is the first official look at whatever phone we spotted late last month, but the only identifying mark anywhere is a PD26100 model number. Based on the test reports, we know for sure that it'll boast Bluetooth, 802.11n WiFi and support for GSM 850 / UMTS I and II, but it's obviously still up in the air as to what carrier this will be headed for. Given AT&T's own proclamation that it's aiming to be the "premiere carrier" for WP7 in the States, we'd reckon that this bugger has a better-than-average chance at sitting quietly beside Apple's iPhone 4 and Samsung's Cetus in due time. Those "holidays" are drawing ever closer, you know?
