In the coming weeks, five Windows Phone 7 smartphones will be available for purchase, all from T-Mobile and AT&T; CDMA versions of Windows Phone 7 handsets for Verizon and Sprint will launch next year.

Starting from the left, there’s the Samsung Focus, a 4-inch AMOLED Windows Phone 7 smartphone headed for AT&T on November 8th.  Next, there’s the Dell Venue Pro (aka Lightning), which features a vertical sliding QWERTY keyboard and a 4.1-inch AMOLED touchscreen; the Venue Pro will work on T-Mobile, but sold by Dell.  In the middle, the LG Quantum, the smallest phone of the group.  The Quantum will be sold by AT&T in late November or December and has a 3.5-inch touchscreen and a slide-out QWERTY keyboard.  Second to the right is the HTC Surround T8788, also from AT&T, which features a slide-out surround sound Yamaha speaker behind its 3.8-inch display.  Last, but not least, the T-Mobile HTC HD7, an update to the HD2 with a large 4.3-inch Super LCD display, will be available in mid-November.

All of the Windows Phone 7 launch devices above have 1GHz mobile processors, 5MP autofocus cameras, 802.11b/g/n Wi-Fi, Bluetooth 2.1, and GPS.

There are more phones running Windows Phone 7 on the way; these are merely the first round.  We’ll keep posting as more device information is made available.
