IPhone turned passcode on by itself?

IPhone has set the passcode on by itself. I don't know the passcode and I don't want to reset the phone as it has important stuff on it.

Book an apple genius appointment. There they can tell you exactly what's wrong and fix it. I can tell you one thing though - there's a 75% chance you will have I reset your phone!

  • My iPhone turned itself off My iPhone 4 turned itself off. I tried turning it on, the normal way, and that did not work. I tried holding in the sleep and home button. And that also did not work. I tried connecting to my iTunes with my usb cord, and even that didn't work! What do i do?
  • My iPhone turned itself off and back on? An hour after I completely reset the phone, the phone screen went dark and then the Apple logo appeared again. So it seems that my phone just turned itself off and back on… But does anybody have any idea why? It hasn't happened since, though.
