So, I thought this would be fixed by now but Find my iphone is still flawed.. there's not a simple way to add a restriction to avoid anyone turning off the Find my iPhone service. you can restrict changed to location services, and you can restrict the icloud account from being deleted. They should have added a simple restriction "Keep Find my iphone always on". What's worse: they added a new restriction for "Find my friends" so that no changes can be made. Why did they make it so simple for Find my friends but not for Find my iphone? I dont' get it.
