For reasons i cannot discuss on this site, my jailbroken iPod touch would not turn on even after rebooting it in DFU mode and long story short, i ended up having to restore with official apple firmware (2.2.1) to get it to work. Now I want to jailbreak it again. I used this tutorial: http://www.ifans.com/forums/showthread.php?t=137683 and it was pretty good. My question is do I have to delete the files i downloaded from there and then redownload them and follow the steps or should I keep the files? Please only answer if you've used this tutorial before. Thanks!
