It seems that Apple might have a problem with their iOS 7 mobile operating system if the video below is correct and works on any iPhone device.
As it shows a fairly simply way of disabling the iPhone’s supposedly secure Find My iPhone feature without the need for an admin password. Watch the video after the jump to learn more and see the iOS 7 glitch in action.
All you need to do is tap both “delete account” and the switch to disable Find My iPhone at the same time in the iCloud settings panel. When prompted for a password, then hold down the power button and shutdown the iPhone and reboot it.
You can then enter the iCloud settings panel and remove the account without being prompted for an admin password. To make this hard for unwanted parties to carry out make sure you always have a passcode lock on your device or this could happen to you if your iOS device gets lost or stolen.
