YES... Question do you think something like what happened with Android could ever happen to a IPhone?
No, because Apple doesn't allow apps that haven't been vetted in their walled garden.
This is the downside of having an open and free operating system, you have no control of it.
The second reply was from a guy that’s saying because he has a iPhone he doesn’t have to worry about it
He is speaking specifically about a Unix kernel level access.
