I wish to update from iOS 7.1 to iOS 7.1.2 on my iPad 3. The material I've read concerning making iOS updates with iTunes states that the latest version of iTunes should be used. The latest iTunes version, 11.3, was released 7/10/14. Is it possible to use a version earlier than the latest? I don't think the public library where the updates will be done always has the latest version of iTunes installed on its computers. On 9/18/13, Apple released iTunes version 11.1; the same day iOS 7 was released. Since then, there have been nine updates of iTunes, v11.1.1 through v11.3. Can a version prior to iTunes 11.3 be used to update to iOS 7.1.2? If so, how far back can one go to find a version of iTunes that will support the update?
