So I want to jailbreak my 3.1.2 2nd generation ipod touch on a mac os x 10.4.11. I got pwnagetool 3.1.4 and I made the installer package. Now am I just able to go into dfu mode and shift-restore? I'm asking this because on the website it says next to 2g ipod "Use PwnageTool to create a firmware image and restore with that .ipsw to your already jailbroken device using iTunes." Is this saying this only works if you have an already jailbroken ipod? Also on videos it showed the program showing how to get into dfu mode. I know how to get in it, but im wondering why that isn't happenening on mine.
