If I downgrade my iTunes to a very old version and attempt to install 6.1.2 custom ipw files, will it work? Thanks in advance. Most articles I read state I cannot update cause iTunes will prevent me, However, no article discussing downgrading iTunes to a very old version, then updating to 6.1.2, then restoring the jailbreak.
