I synced my Facebook contacts with my address book contacts which worked great. However, I am not able to figure out how to join two contacts. For example, in my phone I have my Mom listed as Mom. On Facebook, she is listed as her name. I would like to merge these two entries in my contacts. When I follow the directions NAMELESS gave, the search is not associated with joining two contacts and doesn't know what to do with it. When I press 'join,' it's a black screen with Join at the top. Any suggestions?
