@kev : I think the point is NOT about getting rid of your iPhone, but, instead, being able of getting rid of Apple (in your case), Google (for lot of other people), Amazon (think to Alexa) and similar companies.
If you're unable to live your life without real alternatives to services those companies are offering, than I think this is the first problem to address.
As for myself, I started #degoogling myself ~2 years ago. Currently, with a common smartphone. Not an easy task, unfortunately :-(
