Once the Silarm application is installed in your Blackberry smart phone, it will
be even smarter! Set the application to vibrate or mute mode and every
time you have an appointment set in your smart phone
calendar, disruptive ringer noises will be a thing of the past, even if
you forget to turn it off ! And yes, you will still be allowed to
receive calls if you are expecting an important one. We often also
forget to turn the ringer back on after important meetings. Silarm will
ensure that doesnt happen again.
