Is it possible for me to downgrade to 4.0.1

[g0tvtec]

I have an iphone 3g with 4.0.2

I bought it used and it was already like that. Is it possible for me to downgrade it without the SHSH file?

well, you can downgrade to 3.* or something..... but you do have to have SHSH's for anything 4.+ for all "newer" devices

If this was done before august 19th then it sounds reasonable.
