I'm sorry if this question has already been answered, but I couldn't find it when I searched. I'd like to have a custom ringtone for some of my contacts, such as wife, office, friend, and then the default contact for the rest. I need to know how to load new ringtones and assign them to certain contacts. Do I need an app or can I do this already? Thank you. I have android 2.1 on an HTC Hero.
