An App for Silencing Speed Dialing?

Is there an app out there that will COMPLETELY SILENCE the dial tone? I want it silent even when using speed dial. On my 8320, I was able to modify the "silent" profile so that I would get all rings & tones but completely silent dialing. I cannot seem to do that with my 9700. Any tips or apps out there that would accomplish this?

Not sure if this is exactly what you want but there's an app called Iconify available here:

Iconify [15-Link-Version] - Create Web- Dial- & MailLinks directly on your HomeScreen - Personal Productivity BlackBerry Apps - Crackberry BlackBerry Apps Store

You can set up Icons for speed dial recipients and one push gets them dialed with no noise!
