If your screen was inaccurately positioning presses, it means that your digitizer was messed up in some way. On the hero, the recalibration is strictly for the software keyboard and aids in the word correction algorythm when you hit the wrong letters. It has no bearing on the interaction with the screen, just how to fix words when you screw them up. Capacitive screen can be calibrated at the factory and, barring a hardware issue, will always turn out exactly the same because the digitizer is electromagnetic. On a resistive screen, there is variation in the resistence of the plastic and therefore cannot be consistently calibrated at the factory, so they make you do it yourself. Hope this helps.
