    you can wait until they have a jb for 4.0.2. or check to see if you have shsh files saved in cydia using tiny umbrella.

    Still, check with Cydia if your SHSHs is saved. Some people have reported that they have their SHSHs saved in Cydia eventhough the device was never jailbroken.

    Download TinyUmbrella (http://cache.firmwareumbrella.com/umbrella-4.02.05.exe)

    Run TU, connect your iPhone and click on the advance tab, choose firmware 4.0.1 for the 3Gs. Make sure you select Cydia-Saurik as the repository and click on Save my SHSHs. If the SHSHs is stored in Cydia, then you are in luck and you can follow the thread in this site on how to downgrade.
