Hi everyone. I just recently got an iPhone, and in order to take advantage of some of the cool features of it, I've learned that it's important to have a detailed and well-maintained contacts database. Here's my problem - between Gmail, Hotmail, my Exchange account at work, the address book on OS X, and my Outlook client, I've got a total mess on my hands. When I look for contacts on my iPhone, I sometimes see several listings for the same person, each with different bits of information. It seems that I will have to buckle down and rebuild from scratch. Ideally I'd like all my personal contacts in a single place that I control, and all my work contacts on my Exchange account. What would you guys recommend that I use for my personal contacts? The OS X address book? That will sync with my iPhone, I think. But I don't think it will sync with my Outlook, will it? If I put them in on Outlook, how would I get them to sync with my phone?
