I accidentally somehow bricked my old iPod touch a year ago when I jailbroke it. I don't have too many detail's on exactly what I did to do so (although I did use phone explorer to mess around with some files, bad idea) and I restarted my iPod and it wouldn't load past the apple logo. I tried putting into DFU mode and every other trick in the book to restore it but to no avail. Even the geniuses were scratching their heads. So my question is: How do you make a backup to restore to if things go haywire? I read an article a while back that said there's a way top make a backup or something through cydia to restore to if things go wrong. Forgot what it was called though. edit- I'm not looking for a fix for my iPod, just simply a backup plan in case my shiney new iPhone 4s also dies when the jailbreak comes out.
