a method for sorting everyone who has a custom ringtone. I usually keep my text message notifications on silent, except a few special people like girlfriend, boss, etc. And over time I will some people a custom ringtone if I'm waiting on a time sensitive response. but then I forget to change it back. right now I have about 20 people in my phone book that I can't remember giving them a custom ring tone. basically I want to set most people back to my default notification sound, without checking my entire contact list, or waiting until I get a text from each individual person.
