I've only had my Curve for 3 months so apologies if the answer to this is obvious..
Is there a way to set the BB Curve so that it continues to make periodic audible alerts after a call has been missed? I don't want to have to keep checking the screen to see if I've missed a call or VM.
No need to apologize. This phone had me so crazy I went out and bought a Blackberry for Dummies Book! You should be able to personalize your alerts this way:
Click on your help icon, notification profiles, custom notifications, set custom for messages. It will give you specific instructions from there.
