Is it possible to downgrade from 4.0 to i guess any other firmware? I have a 3g that is unlocked so I can use T-mobile and i heard 3.1.3 is unlockable. Please help 4.0 is draining my battery and is terribly slow.
you should select the 3.1.3ipsw file then it will run and get an error which is normal so you know.
