Why is the iPhone 4 can be powered off when the phone is password protected? The find my phone is of very little use it a thief turns the phone off.
As soon as the phone is switched on again and logs into the mobile network, you can track it again, unless it has been restored.
Restoring and switching off the device can't be protected by a password.
But you can tell Apple about your wishes here: Apple - iPhone - Feedback
