The iPhone 3GS is now supported in PwnageTool 3.1.3, assuming the phone was pwned at 3.0 or 3.0.1 – PwnageTool does not support the 3GS out of the box. If your iPhone 3GS has 3.1 preinstalled and is not Pwned then there is no tested jailbreak solution at the moment.
This means that if you updated to 3.1 or if you bought your iPhone 3GS with OS 3.1 already installed, you will not be able to jailbreak. However, if you are on a pwned version of 3.0 or 3.0.1 (either using PwnageTool, RedSn0w, or PurpleRa1n), then you are fine.
Good news for iPod Touch 2G users! PwnageTool will also support this device.
The iPod 2G is now supported in PwnageTool 3.1.3, assuming the iPod 2G was pwned at 3.0 or 3.0.1 – PwnageTool does not support the iPod 2G with 3.1 software out of the box.
PwnageTool is for Mac OS X only. There is no Windows version yet but let’s hope the Dev Team works on this in the near future.
I will be working on a tutorial and post it on the blog asap. Visit the Dev Team blog for full information on the release.
