It seems that the Dev-Team is at it again.The 3.1 firmware for the iPhone 1st Generation (2G), the iPhone 3G and the iPod touch 1G can now be jailbroken in Mac OS X with a Windows version to soon follow…

This is the low down on our tools for use with the 3.1 firmware from Apple, please read the whole post in full before attempting anything. Because of changes with Apple’s update techniques (that complicate the 3GS upgrade process) this will be a multipart release. This release starts with PwnageTool 3.1 for Mac OS X – this application supports the iPhone 1st Generation (2G), the iPhone 3G and the iPod touch 1G. NB: THIS DOES NOT SUPPORT THE 3GS OR 2G/3G IPOD TOUCH. redsn0w for Mac OS X and Windows will follow sometime in the near future, please don’t bug us about it – we’ll release when we have something ready.

Keep in mind that YOU are assuming all responsibility if you attempt to jailbreak your iPhone so be careful and READ the directions FULLY.
