the solutions been posted already.

drop the .wav file into the windows folder.

I also recommend you make you notifications short, because windows mobile will play the ENTIRE notification when you get a text, and there isnt a way to stop it til its done. so if you get 3 texts back to back your phone is going to sound real loud and annoying cuz the same song will be playing at the same time with 3 different starts and ends
