When i got my new phone, all the contacts were transferred over from my previous phone. I also have all my contacts in Google. When Google sync'd to the phone it created a duplicate of all the contacts. Is there a way to delete all the phone contacts so that all i have is the google contacts, which is what i use as the "master". I know i can reset the phone to factory defaults but i have a lot of apps, music and pictures on there that i would prefer to not have to try and backup and reload.
