Need program to change SMS alert tone automatically - does it exist?

[Juggernaut62]

Hi,

I need a program that will allow me to change the SMS alert tone depending on the time of the day.

I have found programs that let me turn it on or off or change the volume depending on the time of the day, but nothing that will let me change the actual sound of the SMS alert. I have found programs that let me do this for the email and phone alerts, but none for the SMS alert tone.

Can anyone direct me to a program that will let me change the SMS alert tone depending on the time of day?

Thanks!
