Title should have been "iPhones are hard to use - For old people", it's bad for them, but it's not the fault of the iPhone itself, I bet if you give them any other piece of technology it will be equally hard for them.
You are right in pointing out that it could be better, I think that the "Tips" app can have a dedicated section for accessibility features and video tutorials on how to use certain features of inbuilt apps.
They could also have an app dedicated to Accessibility features, pull out the existing accessibility settings from Settings app and show them one at a time in a UIPageViewController inside that app.
