> iOS devices do not update on their own without any user intervention. In order to schedule an overnight upgrade, you have to agree to it then enter your PIN... iOS devices will download a 800M update package over and over again, and then present you with the option of installing the update now, or between 2AM - 5AM the next day, at which point you must enter your pin, and only then, can you decline. > That statement makes no logical sense at all. The reaason they prevent downgrades are to reduce support costs, to ensure broad compatibility, and because of security flaws in older versions. They are clearly making an intentional choice with how they deploy updates. The ability to roll back updates is not difficult. They clearly do not want users to even have a chance to think about whether they want an update. And they certainly are not going to clearly explain how an update would remove features and degrade their UX.
