For some reason it does not work on my Evo 3D CDMA. I'm running the latest 4ext (1.0.0.5 rc3 or something like that). It asks me about the "Alternate touch", I hit the power button (I've tried both answers), then on the calibration screen, it gets stuck. I hit the power button again, and it takes me to the FM, but does not recognize any touch. I have to pull the battery in order to get out of there.
I have the same setup and it works fine, including the touch. Press the power button to select "No" for the alternate calibration method, and when the dots appear on the screen press each one until it moves. At least for me, the first press caused a ring to appear and it took at least one more press for the dot to move to a new location. Then press the power button when the test screen comes up and you should be good to go.
