That's what I figured at first too, but this line from Apple's open letter says otherwise:
>In the wrong hands, this software — which does not exist today — would have the potential to unlock any iPhone in someone’s physical possession.
This line has been quoted a lot and Apple has not redacted or clarified it. If newer iPhones were not vulnerable to these types of attacks, Apple wouldn't say that they are. Especially since they've openly said that one of their big concerns is damage to Apple's reputation for security and privacy.
