The key does not work
My ideas is that, when iphone is on the lock screen can shut down. when iphone lose or stolen this is a big problem
iPhone 5, iOS 6.1
what do you mean?
when iphone is on lock screen it can be turned off and that is a problem or?
if you mean that it can be connected to a computer and restored to factory settings by the theif
then if it could not then if you forgot your passkey you would be lost and might as well throw away the phone
