Wait for 50 years to unlock Today I wanted to backup my old iPhone which I didn't use for a long time and never tried to unlock it for one year now. It was just laying around. Upon charging and starting it up, I saw this message:

"IPhone is deactivated. In 24.286.924 minutes you can try again"

Why this could possibly happen and what can I do about it?
Date/time was wrong on the iPhone. I bought a new sim, it connected to the internet (and then adjusted date/time automatically) and that did the trick.
