How 3G iPhone OS 4.0 to 3.1.3 downgrade?
I downloaded 3.1.3 IPSW and put the iPhone into DFU mode. When chosen to restore, Windows displays the "restoration Apple iPhone verification. then another window opens telling me that my device is not eligible for restoration. HELP!
Reading this, there is no way to downgrade their iPhone 3G OS 3.13-4.0 You will have to wait for software update and the new spirit that should new 2.0 snowbreeze be coming later this month. Hope, I am also a 3G that I have to escape and release. Good luck. Sincerely, Mr. Climber 98
