How to calibrate G-sensor???

[dusk2dawn]

I remembered calibrating it once b4 it had 2 of those tools with a bubble in in it and u had to try and get it in the middle, there were 1 bar on the bottom/horizontal and the 2nd on the side/vertical. Now i try look all over the device for that setting again but i can't find it anywhere. Does anybody know where to find it or know any app that would calibrate the G-senor???

I didn't know it could be calibrated! I just used the phone tester app to see if its working - spits out some numbers so I guess it is

But sometimes I find the sensor doesn't get it right for the screen orientation. I guess the same sensor is used there as well.

I just flashed Tim's rom (4e) and I found G-sensor calibration under Settings.
