As someone who owns an iPhone, I don't think it's really substantially improved my quality of life. It makes some things more convenient, but doesn't really enable me to do anything I couldn't do before with other separate devices, and it can be a major source of distraction at times.
Would you be willing to test that...? I.e. Would you be willing to give up the iPhone for a dumb phone for 12 months? What if we collectively donated to a charity to make it more enticing?
Not the GP, but I'd be happy enough to do that. Then again, my personal computer is a ThinkPad T41 I bought online for like $100 recently when my T420 died, so maybe I don't count? But honestly, so little of my quality of life comes from tech advances (though I do love me some computer science, and work with computers every day).
I did this a year or three back, and the only thing was that with the amount of travel I did, the mobile maps were too useful. If I didn't travel, I'm pretty sure I'd be fine without a phone.
