    It requires that you saved hashes for firmware 4.0.1, if you didn't no downgrade.

    Also, since you updated to 4.1, you also have the new unlockable baseband which cannot be downgraded (unless you used TU to upgrade)

    So, I guess you aren't "smarter than the average bear". :D Sorry, couldn't resist, no harm intended.

    If you don't have a SHSH on file, you're out of luck.
