Looking very similar to the Nexus One (albeit with a larger top-bezel), HTC's WP7-running Mozart phone has appeared in a video along with some very believable specs. Super-LCD instead of AMOLED, an 8MP camera—par for the course really.
Also listed is a 1GHz Qualcomm Snapdragon QSD 8250 chip, which was used in the Nexus One and countless other phones. It's getting a little long in the tooth, that Snapdragon model, but it's entirely possible that when the Mozart launches, it will have a MSM8655, as we'd heard previously.
It's said to have 8GB of internal memory (with an 512MB ROM), and 576MB RAM. An 8MP camera, presumably the very same we've seen in the last batch of HTC phones, and 3.7-inch WVGA Super-LCD screen are all included too—or so the video-shooter says.
Unfortunately it doesn't look like this phone is running HTC Sense, as we saw last week in another leaked video.
Finally, if you watch the video below, you'll see it can sync up successfully with a Nokia Bluetooth speaker. At least we can now answer your burning question as to whether HTC would include Bluetooth on its first-ever WP7 phone...eh. [WMPowerUser via TheUnwired via Engadget]
