How to save all your contacts from backup.

save.js

function saveAllTheContacts(contacts) {

  var saveContacts = function() {
    // No contacts left, stop saving
    if (contacts.length == 0) {
        return;
    }
    
    var contactData = contacts.pop();
    // if you are restoring from a backup make sure you remove the id's
    contactData.id = null;
    contactData.rawId = null;
    var contact = navigator.contacts.create(contactData);
    contact.save(function() {
        saveContacts();
    }, null);
  };

  saveContacts();
}

saveAllTheContacts([{"name":{"givenName":"Test1","formatted":"Test","middleName":"Test","familyName":"Test","honorificPrefix":null,"honorificSuffix":null}},
{"name":{"givenName":"Test2","formatted":"Test","middleName":"Test","familyName":"Test","honorificPrefix":null,"honorificSuffix":null}},
{"name":{"givenName":"Test3","formatted":"Test","middleName":"Test","familyName":"Test","honorificPrefix":null,"honorificSuffix":null}}]);

When I removed id, rawId... and other fields I got it working. It wasn't problem with your code, it was my JSON data (iphone export). I just created new Object with only name and phonenumbers, it is working OK.
