iOS 8 Update
The recent Apple release of iOS 8 has been tested to work with campus wireless and email services.
If you had problems freeing up enough space for the installation, DoIT recommends connecting your iDevice to a computer and updating through iTunes. This requires only 1 GB free space (as opposed to the 6 GB when updating wirelessly). For more information see Update Your Device Using iTunes.
