Thank you. I think that there is actually no function to make the tone. I have had blackberry devices since early 2000 and I have never had one that did not have the notification. I dont think that an app can do it until the programmers actually make the function. It has gotten me into trouble twice today already missing stuff. Overall i think that this is the best thing that RIM has done, gorgeous device, I can not understand how they overlooked this. I have to take it back in a few days if there is no fix coming.
