When I set up the phone, I didnt have a Gmail account. When it asked for one, I setup some random named account. Since then I (some how) have added a total 3 account to the phone (not including my yahoo and Facebook account). I have contacts put in some random formation across all 3 account. How do I move all contacts to a single Gmail account, and delete the old accounts from the phone, leaving just a single gmail, and my facebook?
