Must read – According to the Dev-Team Blog:

iPhone 3GS
Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the 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.
If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.01
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.
IMPORTANT! Whenever you need to enter DFU mode, you will need to do so using PwnageTool.
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.

Select the iDevice you want to jailbreak, either “iPhone” or “iPod Touch”
PwnageTool will now automatically detect the correct firmware for your selected device, but if it doesn’t then press “Browse” button and select the “iOS 4.0 .ipsw” firmware file you’ve downloaded in “step 5″
