A free program for Android, by Sarjudas TuneMaker.
The Kannada Caller Tune Song app has been designed with the user in mind. You can easily change your caller tune with a variety of options in the settings menu. The options are pretty straightforward, and the app is very easy to use. It's a good idea to make a backup of your favorite tunes before trying to change the ringtone. You can also use the app to set a particular contact's ringtone with a Kannada tune, which is something that is not possible with the built-in ringtone options.
The app also has a special section for the contacts you have saved in your phonebook, which is another thing that is not possible with the built-in options.
