Finally the Dev-Team has released the PwnageTool 3.1.4 for Mac OS X which supports the 3.1.2 release of the iPhone software for iPhone 2G/3G/3GS and iPod Touch 1G/2G. The latest PwnageTool 3.1.4 allows you to update your iPhone Firmware without changing the baseband. If you had already upgraded your iPhone 3GS with 3.0 or 3.1 firmware to 3.1.2 using Apple’s Firmware, then your baseband will be upgraded from 04.26.08 to 5.11.04 and the baseband cannot be unlocked.

So if you are a Mac user, you can download PwnageTool 3.1.4 to upgrade the firmware of your iPod or iPod Touch from 3.0/3.1 to 3.1.2 without changing the baseband. After you had successfully jailbroken your iPhone, you can use ultrasn0w to unlock it so that you can use a sim of your choice.

The iPhone 3GS is now supported out of the box in PwnageTool 3.1.4. The iPod 2G is still supported in PwnageTool 3.1.4 but it must already be jailbroken. iPod touch 3G is NOT supported with the current release. If you have got an iPhone 3G/3GS with 3.0, 3.0.1 which is redsn0wed or an iPhone 3GS with 3.0, 3.0.1, 3.1 which is Pwned then you can use the below procedure. But if you have got an iPhone 3GS with 3.1, 3.1.2 which is blackra1ned then you can just jailbreak but can’t unlock the device.
