Devices Supported By PwnageTool 4.01
The iPhone Dev Team have released the latest version of their PwnageTool 4.01 for Mac OSX. PwnageTool 4.01 works only with official iOS 4, not iOS 4 GM. There are several scenarios that you need to be aware of before using PwnageTool to jailbreak your iPhone or iPod Touch. Here we are listing all of them for your convenience:

1.iPhone 2G, iPod Touch, and iPod Touch 3G: Not Supported.
2. iPhone 3GS: Only works with a previously jailbroken iPhone 3GS on old bootrom.
If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode.
3. iPhone 3G:
If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.01 and restore from recovery mode or DFU mode.
If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.01 ipsw using DFU mode.
If you have a Jailbroken 3.1.3 iPhone 3G it is very possible that this can fail from recovery mode, if this failure happens you will need to restore using DFU mode.
As an alternative to PwnageTool, you can use redsn0w on iPhone 3G (on both Windows and Mac) as mentioned in our last post.
NOTE: Whenever you need to enter DFU mode, you will need to do so using PwnageTool.
4. iPod Touch 2G:
If you have an iPod touch 2G (non-MC model) that is jailbroken (but not with Spirit) then you can restore using recovery mode.
As an alternative to PwnageTool, you can use redsn0w on non-MC iPod Touch 2G (on both Windows and Mac) as mentioned in our last post.
