    I can confirm that I was able to downgrade my Iphone 3GS from 4.0 beta to 3.1.3 (since I did not save my SHSH files) by going to DFU mode and restoring the old firmware using the new ITunes 9.2, The restore fails half way when it tries to downgrade the baseband (which we know does not work). After the restore fails, it puts your phone on the recovery mode loop, to get out of this, I just ran blackra1n when it was on the recovery mode screen, this led to the screen going blank. Keep the sleep/wake and home button pressed until apple logo shows up and it should take you to your home screen eventually. I am currently on 3.1.3 with the new base-band 5.13.03. Hope this helps all the user's here.

    I did this a week ago, it does work, but I got out of recovery loop using irecovery, which on 7 64-bit is a pain.
