If you have the curve you can check see how in this interactive demo: http://www.blackberrycurve.com/8300demo/. To see specifically about the ring tones menu, choose ringtones, then change profile ringtone, this will show you how to go in and change the setting. There is a setting to show the settings for when you phone is in the case. Also, did you recently get a new case or are you using the case that came with the BB?
