I will apologize upfront if I have missed this post but I have read all through (I think) and can't find the answer. When I am talking on my backflip and someone calls me I cannot hear the notification beep, but I do have a missed call and/or voicemail notice in notification bar. I have about decided that this ole body has wore out these ole ears - its probably there I just can't hear it. Thanks for any answers....................Jim
