How do I display all my contacts in separate groups?
I have just synced my new iPhone 5 with my MacBook Pro. The iPhone successfully lists all my contacts, but they are now displayed in one long list. However, my previous iPhone 3GS listed contacts separately in various groups. Nevertheless, when I select "Groups" in the upper left of the app, it does list the previous groups. Note that contacts on my Mac are listed in separate groups.
Suggestions?
MacBook Pro, Mac OS X (10.7.4)
