No camera accessible!

Question

am experiencing the problem, that when I execute the code from the documentation in my iAd, it says that 'undefined' is not an object, evaluating window.ad.camera... Maybe, I am using a newer version of iAd Producer than that code was made for (i am at v4.1). Any thoughts?
The variable iAd.Image.cameraAvailable also seems to always defaulting to false... Do I need to initialize the camera via camera.present(reason); somehow? That's not been done in the example from the documentation...
I figured that the Mac Mini I am using to develop doesn't have a built-in camera, so I downloaded iAd Widget Tester on my iPad and tested the iAd on it... Unfortunately with the same results. I am pretty sure that the iPad has 2 cameras, so why is iAd.Image.cameraAvailable always giving false?
Here's the code I used, which I got from the help system:
this.onViewActivate = function (event) {
     camera = window.ad.camera;
    if(!camera)
         alert('No camera accessible!');
    camera.present("The app would like to take a photo!");
    if (iAd.Image.cameraAvailable) {
         // setup our delegate
         var my_delegate = {
             imageActionDidComplete: function (action) {
                 // camera image taken, access url
                 var result_url = action.url;
                 alert(result_url);
                 this.viewController.outlets.image.url = result_url;
             imageActionDidFail: function (action, errorCode, errorDetail) {
                 // something went wrong
             imageActionDidCancel: function (action) {
                 // the user cancelled taking the picture
         var camera_action = iAd.Image.captureImageFromCamera('Take a picture', iAd.ImageAction.CAMERA_DEVICE_REAR, my_delegate);
     } else {
         alert('No camera availible');
Thanks in advance for answering and happy New year, Holger

wjosten,
Thanks for the tip, but resetting the phone does not help.  More detail to the problem...
When taking a picture the photo is captured at the lower left corner indicating that it has moved to the camera roll.  The picture can be accessed by clicking on the photo and it seems that everything is normal.  Clicking on the "camera roll" icon shows an "All Picture" view and I can see the photo that I just captured as a pic icon.  However, when I go back to the home screen and select the "Photos" app none of my most recent photos are in the "Camera Roll".
