A permanent unlock for all devices.

Most of you know about factory unlocks. Well, 3.1.3 can be Jailbroken now. If you had a 3GS, and know someone has a factory unlocked 3GS, well its kind of obvious from here. When you're Jailbroken you have full access to your devices filesystem. If you Jailbreak the iPhone thats been factory unlocked, and you Jailbreak the one that needs an unlock, copy the contents of the factory unlocked iPhone, delete the contents of the locked iPhone, and paste the contents of the unlocked iPhone into the locked iPhone. Now you have an unlocked iPhone. And continue to do this every time you need to restore. This has not been tested, and is not guaranteed to work. If you know someone who has a factory unlocked iPhone, tell them to restore it, unlock it via iTunes, Jailbreak with Spirit, install afc2add from Cydia, use an application that can read a phone's filesystem, such as BitPim. And do the above. This way, you will have a fresh 3.1.3 Jailbroken and unlocked iPhone. Good luck!
