Last time you described this situation as "the app store was basically bricked on my phone". That's quite a difference.
I had set up my iphone to only update on wifi, and was travelling for a month or so only using mobile network.
When I tried to get an uber, I realized the app didn't work correctly (the driver appeared to be in the middle of the ocean). Same for other apps.
Games and apps that don't use heavy server code work fine, but google maps, uber, whatsapp, facebook, and some of the KEY things will break eventually if you never update them.
I was not impressed.
The phone might as well be bricked, updates fail and constantly pop up the payment screen, can't install new apps.
It's like having a virus on your phone.
