The dev team has released PwnageTool 3.1.4 for Mac OS X which supports the 3.1.2 firmware release for iPhone software for iPhone 2G/3G/3GS and iPod Touch 1G/2G.

This latest version of PwnageTool can jailbreak iPhone 2G, iPhone 3G, iPhone 3GS and iPod touch (1G and 2G) running on iPhone firmware 3.1.2. The custom .ipsw firmware provided by PwnageTool, can be used to update the firmware to 3.1.2, and unlock the phone, so that it can use any carrier or SIM card.

Following devices are currently supported by PwnageTool 3.1.4:

• The iPhone 3GS is now supported out of the box in PwnageTool 3.1.4 (or if you have upgraded to 3.1.x in iTunes)
• The iPod 2G is still supported in PwnageTool 3.1.4 but you must already be jailbroken (we’ll update this if there’s a big demand from non-jailbroken ipt2G owners)
• The iPod touch 3G is NOT supported

If you are using a iPhone 3G or iPhone 3G(S) with ultrasn0w and rely on ultrasn0w to obtain cellular service then you should only update your device with an .ipsw that is made with the new PwnageTool.
