With the release of the iPhone Dev Team’s PwnageTool 3.1.4 it is now possible to jailbreak everything but the iPod touch 3rd generation on the Macintosh. Blackra1n for Windows is available to jailbreak any 3.1.2 device including the iPod Touch 3rd generation, so your choice is governed by your platform or device.
I tested PwnageTool 3.1.4 this morning and it worked flawlessly with my 3GS. The previous 3.1.3 version for jailbreaking 3.1 had caused me big problems with the phone being unable to connect to the network after installing the modified ipsw.

Second time round upgrading to the modified 3.1 worked fine, and I have been unable to figure out what went wrong the first time.
Apple has released an update for the iPhone and iPod Touch to firmware 2.2.1. This looks to be a bugfix release with no new features, and the iPhone Dev Team has upgraded their QuickPwn and Pwnage tools to handle the new firmware.

Both of the iPhone and iPod Touch jailbreaking apps have been updated this afternoon, and are available for now only as bittorrent downloads (until demand subsides) from the iPhone Dev Team site. Which app you use depends on how you want to jailbreak your device. PwnageTool will create a new restore IPSW file that iTunes can use, and QuickPwn will jailbreak a device without using iTunes. I had previously updated to firmware 2.1 on my iPod Touch so QuickPwn was the best choice. Read more…
