iOS 17.3 is now available for download on all compatible iPhones, as the latest version of iOS 17 has left beta and achieved stability.
The headline feature of iOS 17.3 is Stolen Device Protection, a setting that stops potential thieves from locking you out with only your PIN. Unless you're in a designated familiar location, you need to use Touch ID or Face ID to change key settings, with some also locked behind a one-hour delay to stop attacks of opportunity.
