Downgrade from 4.0.

There may be other, simpler ways to do so, but after hours of testing this has worked for me twice.

-YOU WILL NEED SHSH FILES ON SAURIK'S SERVER FOR 3.1.3 AND 3.1.2.
-YOU WILL NEED TO EDIT YOUR HOSTS FILE TO BYPASS APPLE'S SIGNATURE.

Instructions:

To do this, you'll need the following:
blackra1n
3.1.2 FW for 3GS (this isn't tested on any other device)
3.1.3 FW for 3GS
Pwnage Tool 3.1.5
