There are many different sound schemes for Windows mobile like low battery or any error etc. These settings are not directly available for modification unless you tweak in the registry. Tonality is a free application for Windows Mobile for accessing various hidden sound events deep within the registry that would have been otherwise very difficult for you to access and modify.

Features of Tonality;

• Allows you to modify 52 different sound events
• Add new sound events
• Displays every wav file on your device, no matter where they are stored.
• Allows you to add non-standard sounds such as mp3s if your device supports them
