I upgraded my IPOD from a classic to a touch. One of my favorite features on there is the calendar. I can keep track of my kids soccer games, appointment, meetings etc... I am a true "mom on the go". How do I get it to make a sound when I set the alert? I did a test and if I press the button and look at it the alert shows on the homescreen but if I don't remember to do that how else will I remember? I'm really frustrated there's no sound. Any help would be appreciated.
