turn off iphone should require a passcode
I had my iphone 5 stolen last week and the Police was not able to trace it as the thief turned it off.
If a passcode was required in order to switch off and even activate flight mode, the iphone will stay on and give the robber no alternative but to dump the iphone somewhere for not be traced.
I hope this will not get lost like many other ideas...
To the person who took my iphone: hope you will need more than that in medicine!
