These Nokia phones have a built in ringtone composer and you can compose new ringtones directly on their keyboards. Composing ringtones this way is free, but requires some skill.

You do not need to understand the special symbols that appear on the composer screen as a result. Use the ringtone composer option to enter the key presses into the handset.
