Apple announced in June at the virtual WWDC that it will allow users to set third party browsers as their default web browser in iOS 14. This is currently at 'beta 8', I have a device on this track. Note that Microsoft has also now updated its Edge preview app with support for setting Microsoft Edge as a default browser on Apple iOS 14. Google Chrome is another option, of course. Ubiquitous things just got even more ubiquitous...
If you are running the latest iOS 14 beta, you can download the Microsoft Edge browser here.
So, taking advantage of the battery life, speed, imaging, and so on, of the latest iPhones, you can also run Edge, Office, Outlook, OneNote, OneDrive, and so on. We're getting to the point where the underlying OS and hardware fade into the background while we run the apps and services we want.
