Some of Apple's older devices ran into trouble with the iOS 9.3 update released earlier this week. The iPad 2 took the worst of it; users reported that the tablet was unable to complete the activation process with Apple's servers after being updated. But other products including the iPhone 5S had their own set of problems. They couldn't complete the update unless users remembered the original Apple ID and password used to set them up out of the box. If the device had switched accounts (or owners) at some point, that could lead to a serious headache. So far, Apple has taken two steps to fix the unforeseen problems with iOS 9.3.
