> Get an iPhone and use it in preference to your computer.

When connecting to a computer or charging, never ever tap on "trust this computer". If I understand it right "trusting this computer" involves some irrevocable certificate exchange, in effect granting the computer elevated permissions.

Can someone correct me? What precisely "trusting" on iphone means except from the ability to decrypt backups?

Also:

Don't use icloud or any other cloud sync.
