I must admit that my first gut reaction to this story was to make a joke about the FBI discovering Google and realizing that there are numerous other ways to extract data from a mobile device without a court order.  That said, there are serious implications to personal security is the FBI has discovered or has been given an iPhone Zero-day that can be exploited in the wild.  Many an ethical and social dilemma arise from this conversation.  I suppose we will have to wait and see.
