Great question Moby007!
You can download the Backup Assistant application to your device http://vz.to/YDSEoe to sync your contact list to your device. Once the application is installed, you can manage your contacts online. While the Backup Assistant Plus website still can be used to manage contacts from the web, a manual sync from the device must be started to update contacts on iPhone. I hope I've answered your question and have addressed your concern. Thanks!
