Reading the full thread, nobody got it to work b/c it doesn't work. You can't do a restore on a 3GS with iTunes not connected to the internet, and if you do it gives an error. If you are connected to the internet and do a shift+restore on a 3.1.2 it says device not eligible.

The method doesn't work. Downgrade Iphone 3gs Baseband 05.12.01 from 3.1.3 to 3.1.2 and jailbreak without SHSH - Page 26
