Angry iPhone buyers have started a petition calling on Apple to boost WiFi functionality in the iPhone by adding support for 802.1x, a security protocol used by many school and business networks. The iPhone can't accept 802.1x instructions, so many college student have found it useless with their campus wireless networks.
Looks like the kind of thing that could be fixed in a firmware update, if Apple is listening.
