I just recently bought a 8GB itouch from walmart (like 3 days ago). It said it was itouch 8GB 3G on the website but I have been reading and have seen that there is no such thing as 3G 8GB itouch. It came with 3.1.3. I was wondering if there is anyway to downgrade it to 3.1.2 so I can use this jailbreak http://www.ifans.com/forums/showthread.php?t=259842 . Is that jailbreak good? Also is it really worth it to jailbreak?
