I am trying to edit the host file to point to saurik's server so I can downgrade my iPhone from 4.0 to 3.1.3 but when I edit it and then try to save it I get an error saying I don't have the permissions go to the file then get info and check the permissions.
When I do this and change it so I can read/write to the file then I try to edit it again and save I just get the same error message?
