You must have a bigger (or sharper) phone than I do.
Have you seen the App you get on most large smartphones these days called My Smart Phone is a Weapon. It instructs you how to throw your phone at your attacker to cause the most amount of damage.
im just kidding that doesnt exist, but i wish it did.
Sounds like the sort of app that a certain New Zealand actor could make good use of.
You guys had better check that Naomi Campbell hasn't already patented it :)
