I just got my iphone 3 weeks ago. My contacts synced at first, but now, when I add a contact to my phone or computer, they don't update each other through Mobile Me as I believe is supposed to happen.
Following the directions of the link listed in the previous response
http://support.apple.com/kb/TS1679, I went to my preferences, went to Movile Me, went to sync and now the only option is to replace all data from either phone or computer, or merge, which I am pretty sure will duplicate everything. There doesn't seem to be an update option, the choice to add only what is new to both.
Am I missing something? Thanks for help.
