I have searched through these forums and found My|Profile & Ultra Profiler but really was looking for something even easier (freeware?).
Anyone want to do a little programming?
Here is how it would work.
1. Today screen plug-in
2. One icon or button labeled as "Silent"
3. Using a 'Today Options' button you could select a check box to Vibrate when Silent.
4. When "Silent" is pressed it would set the Volume Settings to 'Off'
That's it. Nothing else, no changable tones, no schedules. Just quickly silence the device. You can then use the Volume Slider to restore your previous settings.
On a related matter I don't understand why I can use the Volume Slider to recover from a "Volume Off" setting. It restores my previous Phone & PDA settings but I can't go to "Volume Off" using the slider. Weird.
