According to a study of over 15,000 Palm, RIM and iPhone devices by Square Trade (link to PDF copy of study) the iPhone was least likely to have a hardware failure. While this may be surprising to some, the iPhone’s first year failure rate according to the study was 5.6% while the Research In Motion BlackBerry devices reached up to 11.9% and Palm topped out at 16.2%. The study primarily focussed on hardware issues didn’t take into account problems fixed by software patches or firmware updates. The most problematic area? Touchpad/Screen/Keypad.
