I got a Iphone 3GS and am having a hard time trying to restore to 4.3.3. I made a custom IPSW for 4.3.3 with Snowbreeze. I am unsure of the current version cause the owner forgot the passcode and the PC where he synced died. I am trying to restore to 4.3.3 and not regular restore to 5.0.1 with Itunes, because I want to preserve the baseband. I have been trying with Itunes 10.1 under 7 (32 bit and 64 bit) and Tiny Umbrella but keep getting error 3194. I have tried commenting out in the host file 220.127.116.11 gs.apple.com. If I set the host as 127.0.0.1 gs.apple.com I get a 2500 error.
