The guys over a BGR have managed to get hold of this picture of what they believe is the LG Xenon, and apparently this LG Xenon is with the AT&T labs undergoing tests.
The word is that the LG Xenon should become available before Christmas, so just in time for the Christmas present rush I would say.
As you can see from the image the LG Xenon is a slider design with a full QWERTY keyboard and features a 3 megapixel camera, UMTS/HSDPA, an accelerometer, A-GPS and WiFi. Sixe wise the LG Xenon measures 105.5 x 53.5 x 15.8 mm.
