I bought an iPod Touch 3G (MC), with 3.13 firmware installed. I jailbroke it with Spirit, but then upgraded it to iOS 4, non-jailbroken. While on 3.13, when I ran Cydia, I remember pressing the ''Yes, make my life easier'' option. Does that mean that I saved the SHSH blobs? If so, would fully erasing the iPod and restoring it affect the saved blobs? Cos if they are still there, I'd like to know how to downgrade my iOS 4 iTouch back to 3.13, to jailbreak it. I tried the traditional way (Hold shift while pressing restore in iTunes, blabla bla), but it didn't work (error 3194). Any help would be appreciated.
