I have a 1st gen iPhone (w/2.0) and my boyfriend just got the new 3G. I would have thought by now they would have added an alert or reminder for a missed call or a text you haven't looked at yet (say after a few min). Does anyone know if this is in the works or if there's an application that solves this? I read about Kate (formerly Caterpillar) but I'm a little weary and don't want to pay for something they may come out with eventually. Thanks!
