Unless you saved the 4.0.1 blobs when you had the chance, no, you won't be able to go to 4.0.1.

It does deal with that signing thing, or SHSH. Apple generates SHSHs for individual phones based on the phone's unique ECID. When they release a new firmware, like they did with 4.0.2, then they stop signing the previous one. In this case, they stopped signing 4.0.1 on August 19.
So, unless you took action to save that SHSH, say, by pressing "make my life easier", it's unlikely that you have the SHSH you need for 4.0.1.
It'd still be worth trying TinyUmbrella to see if the SHSH might be saved on Cydia. It costs you nothing to check.
