TinyUmbrella is the tools developed by NotCom.Its an SHSH saving tool that allows you to downgrade your iDevice’s firmware version to a lower version than you are currently running. This can often times be helpful in case you accidentally update to a firmware version that cannot be jailbroken; as by default Apple does not allow downgrading.
