The wireless network pirate, used by students, faculty and staff for access to the Internet and secure access to the campus intranet, is not compatible with the wireless authentication built into the 1st generation iPhone. Pirate is configured to use 802.1x authentication via PEAP, and the iPhone does not currently support PEAP.
There is an open, publicly accessible network on campus named su-public, but its coverage is restricted to the Smith Library Center, 1st floor and the McCombs Campus Center, 1st floor. The iPhone can connect to this network with no configuration necessary.
