I usually keep my phone on vibrate, but for then past few days I put the spund back on. One thing I noticed is when changed the alert sound for my blackberry messenger it still makes the default alert when i get a message. the sound that it is making is "Notifier_Crystal" which think is the most annoying alert on this phone.
same type of problem, only 1 contact screws up won't beep will only vibrate or flash rest are fine. deleted set up again still the same set up custum profile this 1 still won't behave
