I have a 2nd Generation iPod Touch running firmware 3.1.3 with a model number of PB533LL. Will this affect my ability to downgrade from 3.1.3 to 3.1.2? If not can someone post a link to a GOOD tutorial on jailbreaking. Thanks EDIT: I have found the answer to my question at this link...http://www.ifans.com/forums/showthread.php?t=276351 Thanks to those who have tried searching for me. You can close this thread now if you want because it has been solved.
