I am looking for software that allows me to turn off my phone's ringer for specific periods of time. When I turn the phone off for a meeting/movie/dinner/etc. I rarely remember to turn it back on - not good. I'd like to be able to set it 'Off' for 3 hours (or whatever) and not have to worry about remembering to turn it on again.
If there is such software I will be very grateful for the information.
