I jailbroke my iPhone4 with greenpoision back right after I got it, a few days ago I decided to restore my iPhone and and update it to the latest firmware. I backed it up, pressed "erase all content and settings" now it will not pass the jailbroken sign (skull apple) I assume that is normal. iTunes keeps giving me errors when I try to restore it, the main one being 3194, what can I do to get past this??? Plz help!!!
