I have heard about Apple has started a "soft" SHSH blob checks with IOS 4. I currently am jailbroken with Redsnow and the other day i went into Cydia and it said something about my ECID but i accidently touched the screen and it went away. Was it asking me to save my SHSH through Cydia? and Can i even restore back to 4.0.1 if i need to re-jailbreak? please help. kind of curious.
