"The beta firmware that comes with the iPhone SDK has been modified to unlock and jailbreak the iPhone, even before its public release. Part of the Pwned Project, the hacked firmware will allow you to do anything you want, including the installation of both official and unofficial apps, and even patches. We got the exclusive details directly from the DevTeam, including the fact that it is going to be extremely hard for Cupertino to close this new hole:
'pwned firmware means it's custom [firmware], you can have it install anything you would ever want :-) Pwned works with some magic, it will be hard to close but nothing is impossible (from Apple) with a mindtwist. But first, we will enjoy :)"
