So my iPod Touch was indetified as an 3G when I bought it. It is 32 GB and then one day I was on 3.1.3 and wanted to downgrade to 3.1.2 so I used 2G firmware, worked fine! But NOW! When I want to jailbreak 4.1 f*cking GreenPoison and LimeRa1n thinks that its an 2G!

How can I jailbreak? I tried RedSn0w but it didnt work!
