Beyond it being iOS9, you're able to do so because you've held that phone for a long time and maintained your blobs for each of those versions. It's a rather lofty assumption to believe anyone asking for help with such a task did the same thing. It's disingenuous, at best, to claim they can do what they're looking to do with the 4 or 4s. It's only true in very specific situations. It might be correct in this case. But, it's more likely to be incorrect and give false hope. It helps to stay on topic by noting the relevant information.
