Around 9am this morning, T-Mobile unveiled the first Android-powered "GPhone" to members of the press. See video of the event.

The handset features a touch screen and a full QWERTY keyboard. It boasts a three megapixel camera, one-click contextual search and a zoom-ready browser, as well as wi-fi and 3G capability. Support for YouTube is built-in, as is support for the Amazon music store — which, unlike iTunes, enables users to buy music without DRM protection, typically at a lower cost per track.

Finally, all users will have access to Google's Android Market, a service similar to iPhone's App Store.

The unit costs $179 for existing T-Mobile customers. Pre-orders will be shipped around October 22. T-Mobile expects to unveil the phone in 27 3G markets by mid-November. (According to The BBC, it goes live in the UK "just in time for Christmas.")

A survey of enterprise smartphone users found Android is expected to hold 4.8 percent of the market in three years.
