* The teardown you've linked to is (a) pretty superficial and (b) wrong (though I see it's now been corrected) --- here I will annoy you by smugly noting that you've linked to an exploit teardown written by someone who thinks it's likely that the iPhone would have been vulnerable to an Acrobat Reader flaw.
* It is not generally the impression I get from vulnerability researchers that the iPhone does a poorer job of defending against remote code execution vulnerabilities than Android; specifically: the iPhone has much stricter (DEP-style) page protections than OSX, and the iPhone has strict code signing.
Does Apple need to take security seriously? Indubitably. But I don't think you can read tea leaves here. Things like this are going to happen to every phone. Let's see how Apple handles it; that, at least, is a signal we can actually discuss reasonably.
