PhoneGap developer app - not able to connect to my camera

I have an issue with the PhoneGap desktop app. I wrote a piece of code that accesses the device camera. Using the PhoneGap desktop app it doesn't access the camera on my iPhone. When I build the same code using build.phonegap.com it does access the camera. Here is my code and config.xml files:

    // Get the picture from the camera
    function getPicture() {            
        if ($("#radio-view-b").attr('checked'))
            sourceType = navigator.camera.PictureSourceType.PHOTOLIBRARY;
        else
            sourceType = navigator.camera.PictureSourceType.CAMERA;            
           params =  {
                quality: 50, // from 0 to 100 - size vs. quality
                destinationType: navigator.camera.DestinationType.FILE_URI,
                sourceType: sourceType 
                }
           navigator.camera.getPicture(uploadPhoto, // ** PG **
                function (message) { alert('camera.getPicture failed'); },
                params
                ); 

    }

    // Upload the photo to the server
    function uploadPhoto(imageURI) {
        var options = new FileUploadOptions(); // PhoneGap options object 
        options.fileKey="file";
        options.fileName = imageName; // file name
        options.mimeType="image/jpeg"; // file type
        var params = {}; // Optional parameters in case you need to pass
        options.params = params; // add parameters to the FileUploadOptions 
        var ft = new FileTransfer(); // ** PG **
        var serverUrl = "http://......../ReturnValue.ashx"; // my URL
        ft.upload(imageURI, encodeURI(serverUrl), uploadSuccess, uploadFail, options); // Upload
    }// Upload Photo

    // Loading Successful
    function uploadSuccess(resp) {
        alert("success");
    } 


    // Loading Failed
    function uploadFail(error) { 
        alert("failed");
    }

Config.xml:

        id        = "il.ac.ruppin.pictureUploadApp"
