That said, this week Apple did something a bit out of the ordinary — it rolled out a rare update for some of its very old iPhones.
Have an iPhone 5S or iPhone 6?

That’s right, Apple has issued a surprise software update to iPhones (and iPads) that are considerably older than the models that traditionally receive software updates. Specifically, it’s an updated version of iOS 12.
