Big iPhone 17 security upgrade

🔒 Big iPhone 17 security upgrade: Apple’s adding a new feature called Memory Integrity Enforcement to take on spyware. It’s always running in the background, protecting the kernel and 70+ processes, which makes stealing your data a lot tougher. The catch? It only works on the new A19 chips. Older iPhones will still get a memory safety update, but not like this.
