iOS 9.3 beta 4 fixes devices affected by 1970 bug, prevents issue from occurring in the future
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.
