I have an itouch 2g 4.0 mc model. I am trying to hack the ps3 with it like I saw on YouTube. But the only problem is I need to downgrade it to 3.1.3 or 3.1.2. It won’t work when I go to iTunes and put it in recovery and do all those stuff. Please help me downgrade the iPod. And also explain what to put on it so I can plug it into the ps3 and hack it with the file on the iPod.
