Hi all, I have Yahoo Messenger in my iPhone 4 which works very well. The only thing is that when I leave it online and messages come in the alert tone is so loud that it makes everyone in the supermarket look around. Okay I know I can turn down the volume, but is there any way of changing the default message alert tone? Ive looked in the General settings and also YM settings but I cant find how to change the tones. Any ideas?
