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!

3.1.3 Battery meter problems.

There has been recent reports of battery meter problems with the Spirit Jailbreak on 3.1.3. This has nothing to do with Spirit. This is Apple's fault, and was fixed in the 4.0 betas. In the 3.1.3 update, it included an update to make a more accurate battery meter, and to do that Apple had to tamper with the battery meter settings. This screwed up the battery meter, and made it all inaccurate until 4.0 betas. They released 3.1.3, and used the battery meter accuracy excuse to cover for the baseband exploit plug that was also released. This forced users to either sell their iPhones, or switch to an official carrier if they were on a non-official carrier. This has nothing to do with the Spirit Jailbreak as said before, and should be known that Apple already has a fix. I don't even notice the problem anymore, as I think it went away due to calibration. That might be something to try.
