"No it's at what point Apple will patent the bulletproof phone"
Note that despite Apple's pride in the aluminium back, the article does not say that an iPhone has ever stopped a bullet. For a variety of reasons one would think there would be more incidents of iPhone users being shot at, too. Obviously it's the smaller screen size - less chance of it getting in the way.
(Cue quote from the spectre of Jobs: "iPhone users would rather be shot than use a device with a larger screen.")
