iPhone 5 and jailbreak difficulties

Breaking the iPhone 5 is going to be tougher than ever but perhaps not impossible. Old attack vectors have been strengthened.

Using the kernel’s debugger through a serial port (this is only accessible via a serial connection) will be difficult. Access to the older iPhone devices was possible by piggy-backing the 30-pin connecter as that had 2 pins set aside for serial Communication.

I’m almost certain now that the new Apple Lightning connector will not have the dedicated serial pins. This will need to be reverse engineered.

Even if iOS 6 has vulnerabilities (and we don’t yet know if it does) entry points into the A6 SoC will have been checked and checked again by Comex in the last year.
