It doesn't matter how easy a particular procedure is on an iPhone or anything else if the person trying to use it is so scared of technology that they don't even try.

I know many people (yes, most of them older) for whom the idea of trying to look at an unfamiliar process on a computer (including smartphones) and see if it's something they can do themselves is just a completely alien idea. If it's not something they're already familiar with, it's Scary Technology Stuff, and they need a Technology Person to handle it for them.
