Does anyone else have a problem hearing the email notification beep? I was with a blackberry user yesterday, and when he got an email, we could all hear it even with some crowd noise. Not only is the blackberry beep louder, but it also lasts longer. I wish Apple could increase the volume by a large margin (for all sounds on the phone, not only email notification), but also increase the length of the sound. I'm sick of noticing emails that I receive hours earlier that I missed because I didn't hear the notification beep.
