Modern iPhones are entirely encrypted while locked. The key resides in a crypto processor and is irreversibly destroyed during a brute-force attempt (provided you have this turned on). These devices need certain plists from the phone's trusted iTunes library (if it even has one) to "break" into modern iPhones. (Some) Android phones might be vulnerable to these though.
