I have a 2nd Gen touch and so far have been very happy with it and am pretty impressed with the all round function, however...the other day I installed level lite which made me notice that my horizontal leveling is out by about 8 degrees! so when I started to try other apps with precision control using the accelerometers I had not the control I need. I am frustrated with its in accuracy and am sure this great technology shouldn't be flawed in this way. Its never been dropped or knocked, unless it happened before sale? I know that labyrinth has calibration but it only seems to calibrate for the game so the error is only compensated, well that's not good enough the whole thing should be functioning! I wondered if there is any way to re-calibrate the sensors? oh and a reinstall and a reset has no effect. Any ideas I would be most grateful for, or I might have to go back to the store!
