Earlier this month an odd issue was discovered that could potentially brick any iOS device. Essentially, if you used the Settings app to change the date of your device to January 1st, 1970 and rebooted it, any 64-bit iPhone or iPad would be basically bricked. A handful of fixes floated around, but the general consensus was that visiting an Apple Store and getting your device replaced was the best way to solve the problem. Now, as spotted by MacRumors, Apple appears to have fixed the issue with the latest iOS 9.3 beta.
Users have noticed that if you have a device stuck in a boot loop due to this issue, you can successfully use iTunes to restore to iOS 9.3 beta 4 and your device will boot as normal. Previously, performing a restore via iTunes would not fix the issue.
Furthermore, iOS 9.3 beta 4 removes the ability to set a device’s date to anything prior to January 1st, 2001, ideally preventing people to cause this issue in the first place.
iOS 9.3 beta 4 was released earlier this week and includes small changes such as a new Night Shift icon and new star icons next to track names in the Music app. Also also announced earlier this week that the next beta of iOS 9.3 will bring back the ability to use Apple Pencil to navigate iOS.
