No matter what I do to the settings, there are no notification sounds playing for any calendar appointment. Also no onscreen message for any appointments or alarms. Soft reset as well as battery removal yield an amazing thing: upon startup, it's as if the days or weeks worth of notification sounds all play at once... often over the course of 5 minutes, the phone beeps and chirps in huge spurts. Can't figure it out, don't want to do a hard reset. Help?
