Mac Terminal Permission Denied

[Ipsofacto73]

I'm attempting to duplicate the functionality exposed by Apple’s signature server, by entering (/private/etc/hosts) into the command line of Terminal Bash. I'm doing this to downgrade the firmware in my iphone 3gs from 3.1.2 to 3.0.1. I've been receiving a (permission denied) response for my efforts. I've gone into "Disk Utility and added myself as a "root user". However, that doesn't seem to correct the permission denied issue. Perhaps I didn't correctly add myself as a root user. Any help that you all can provide will be greatly appreciated.

Thank You
Peace
