Its high time I got my Mac's address book contacts into some kind of useful order. I don't use them much on my Mac itself but it's invaluable when synched to my iPhone. I was just wondering if there are any 'helper' apps for use with the standard 'Address Book' app to help me get things sorted? I could do with some features such as 'show/hide contacts with no phone number', also the ability to sort contacts by things like date added/modified or by date last accessed/called..... Also the ability to find/remove duplicates based on name, number, email address etc would also be very helpful. Anyone know if such an app exists?? Or do I just have to do it all the hard way?!
