I recently acquired an Augen Gentouch78. The model I got: NBA7800ATP When I took it out of the box, it was basically unusable as the touch screen was way off, and the built in calibrator did not work. Also, I was unable to connect it to my google account (the gmail app wasn’t there), and the android market was also MIA. Fortunately, I found a patch and the instructions (which of course weren’t bundled together).
