All OS updates are signed If what you are saying were possible, then all phones would always be susceptible to a man in the middle attack of someone faking apple’s server to send a fake OS update. All this seems to be is a qi charger that has the ability to also turn the phone on / off then it can just connect to apple’s server and update itself like normal.

Honestly the only real world differences are the camera and battery life. If you are a medium to light user the non pro battery will last all day and then some. So if you are a very heavy phone user or just care a lot about the camera get the pro, otherwise not worth it.

The difference here is that the data exists still and can be played via emulators still. However, it violates copyright laws to do so. It has nothing to do with “time destroying all works” (at least not yet)
