This has nothing to do with upgrading to IOS 5. You can restore the firmware. If you want to upgrade to IOS 5, you'd better back up your current version of SHSH. It is estimated that it will take some time for the perfect jailbreak of IOS 5. If you regret it, you will be downgraded, otherwise you will not be able to get down!
