iOS 10 has just dropped but it seems like it is not smooth sailing for everyone. We have received many reports that users are finding their iPhone and iPad devices ‘bricked’ after attempting the over-the-air iOS 10 update. To restore, affected users must then plug their devices into iTunes on Mac or PC to restore the device.
Details are sparse at this time but the issue appears to be related to the fact that the OTA attempts to download iOS 10.0 and then iTunes updates to iOS 10.0.1. We are tracking the story and will update if we hear any more details about this issue.
