Apple fixes iOS 9.3 activation bug
Shortly after Apple released iOS 9.3, users of older devices started to face activation issues. Fortunately for them, Apple was very quick in solving this issue. The problem was pretty hard to reproduce, so it is good to see that the Cupertino giant also made things clear regarding the circumstances under which this bug occurs.
According to an official support page, "Updating some iOS devices (iPhone 5s and earlier and iPad Air and earlier) to iOS 9.3 can require entering the Apple ID and password used to set up the device in order to complete the software update." Apple outlines two approaches, one that involves making sure the Apple ID is entered correctly, and the other the removal of Activation Lock.
In addition to the workarounds mentioned above, Apple also issued an update to iOS 9.3. This build is still iOS 9.3, but the build number is 13E236 instead of 13E233 for the original iPad build and 13E234 for the iOS 9.3 original build for iPhone. The update can be done via iTunes or over the air, as usual. At this point, it is not clear yet if the update solves the problem only for the iPad 2 or all affected devices, but we will get back to it as soon as we find out more.
