yes , apple closed issuing the 4.0.1 shsh last few day.
unless u did backup shsh 4.0.1
otherwise u need to stay the later firmware 4.0.2
which is not ready for JB ( except iphone 3G or 2G ? )
google it , u will get more info

Sorry But the bad news is that you cannot downgrade from now cause apple has blocked..downgrading

If you saved shsh before August 19 or jailbreaked before then and started Cydia once, you have shsh stored on Cydia. With stored shsh for old firmware, you can downgrade to that version. If you bought a new phone after August 19 that was never jailbroken, you're out of luck. No way to downgrade an iPhone 4 then.
