I keep trying to do this and every time the process gets stuck in iTunes when its trying to verify the upgrade with Apple. Then it says it can't do that. I tried to sign out and back in to my iTunes account and now i get another messages: this device is not eligible for this build. WTF??? I have a jailbroken iPhone 4 with 4.1 firmware. Did it before with PwnageTool on MAC. No idea what is wrong with this as i've done this since OS 2.0... Any ideas? Anyone?

You need to add : 74.208.105.171 gs.apple.com to your hosts file. And then try to use iTunes again(restore custom). Apple has stopped signing 4.2.1

Thanks for your reply! Just so I understand: i don't actually have to already be at 4.2.1 in order to restore to a custom 4.2.1, right? Someone told me that its failing because of that. Because I'm currently at 4.1. Is this right? I don't need to already be at 4.2.1? If i add this entry to my hosts file - the restore should work?
