LOL at all the idiots in this thread. What the guy did was basically vandalism. He took a piece of property that didn't belong to him and altered it without permission.
It's not legal to JB since the iPhone WASN'T HIS PERSONAL PROPERTY.
Why don't some of you go and hotwire a car in a dealership and see if they think it's funny. Or remove an option from that car and claim you're "improving the vehicle by eliminating a useless feature".
