When initially setting up the iPhone app, I "allowed" the app to sync with my contacts, importing some 800 iPhone contacts that have nothing to do with my business. I tried uninstalling & reinstalling thinking I could not allow access to my iPhone contacts. When I reinstalled the app all my iPhone contacts were already in the personal contact list. Is there an easy way to remove all personal contacts and start fresh without having to delete each one individually? Did it create a contactDAV file that this is syncing with?
