Apple has released an updated build of iOS 9.3 for users affected by an activation bug, first reported last week. Although the version number is still 9.3, the update features a new build number, 13E5237, to signify the change. The issue prevented some iPhone and iPad owners from successfully completing the upgrade steps for iOS 9.3 if they could not recall their Apple ID info immediately, to pass Activation Lock.
Readers are reporting a strange bug with iOS 9.3, primarily affecting the latest Apple devices, iPhone 6s and iPhone 6s Plus. The issue has also been reported on older phones and some iPad models as well. The cause is unknown, but many users are finding themselves unable to open links in Safari, Messages, Mail, Notes and other apps. Instead of visiting the target website, the app crashes, freezes or hangs. Hundreds of reports have already been posted about the iOS 9.3 problem on the Apple Support forums.
