One of the previous posters was correct, you need to re-enter specific contacts that you want to assign specific ringtones to (husband, wife, mom, close friend, etc) and make sure to save them to the green phone icon. Even if you already have them in your phone as a google contact you need to re-enter and save to the phone icon option. When you do that you can specify ringtones for each contact then when you choose to view google, phone, sim, and/or facebook contacts your phone will merge the info. I have home addresses, email addresses saved under google contacts already so you don't need to re-enter all of that just their given phone number(s) and the rest will be merged together when you choose to view phone contacts and google contacts together.
