Microsoft's Aaron Woodman just pulled off a little surprise here at The Engadget Show: he brought out LG's Windows Phone 7 Series pre-production prototype! The QWERTY slider is the first branded Windows Phone 7 Series device the world's ever seen, and while the hardware and software are both obviously early, we can tell you a few things about it: it's just a hair thicker than an iPhone or Nexus One, there are dedicated hardware camera, volume, and power buttons in addition to the back, home, and search buttons dictated by Windows Phone 7 Series, and we noticed a five megapixel camera with a flash on the back, along with a headphone jack. Can't say much apart from that right now, since things are so early and everything is subject to change, but things are certainly moving along.
