It is not clear only the option to change from those that are listed as options in the phone settings are provided.

Get the ringtone you want on your PC. Connect your phone via USB Cable or Bluetooth. Open your phone's memory/SD card, find 'Ringtones' folder and copy/paste your ringtone there. You will be asked to convert the file, choose yes and you're all set.

You can also get bunch of cool ringtones on The Zedge.
