Not all accelerometers are created perfect, and for these the HTC Touch Pro has a calibration utility built-in to correct any issues that may have arisen post shipping. The HTC Touch Diamond however lacked this important software, leaving many users with a poor screen rotation experience and with a Teeter ball constantly rolling to the side.
HTC has now release a hotfix which brings the Touch Pro calibration utility to the HTC Touch Diamond.
