Let me first say that my originally iPhone came with 3.1.3 and 05.12.01 firmware on it... i accidently upgraded to iOS4.0 and my model firmware became 05.13.04... so I followed this tutorial: thetechjournal.com/electronics/iphone-electronics/downgrade-ios-4-iphone-3gs-3g-and-ipod-touch-to-iphone-3-1-3-3-1-2steps.xhtml
and i did all that, BUT my model firmware is still 05.13.04 and not 05.12.01 as it came with factory defaults.
PS YES, i do have 3.1.3 05.12.01 bloobs shsh file saved on my pc!
