Resolving Lockouts on your iPhone or iPad
If you change your network password, and have Wi-Fi setup on either your iPhone, iPad, Laptop or Wireless Device, it will not pick up the new password automatically.
If you have the latest iPhone / iPad software installed iOS4 then you should be automatically prompted to input your new password.
However if you have yet to upgrade to iOS4 then you may find your main computer account gets locked out. In this case you can manually remove then reinstall the connection with your new password. Once updated you will need to get your account unlocked again.

Tap settings then the UoC network:
From the Wi-Fi screen, click the right facing blue arrow next to the UoC netowork, then choose forget this network:
Confirm forget network then tap wi-fi networks:
You have now successfully removed your WiFi account.
