  //Spinner inside the Loop
Spinner spinner = new Spinner(Spinner.IPHONE);
spinner.setForeColor(Color.WHITE);
add(spinner, CENTER, AFTER,, FONTSIZE + 200, FONTSIZE + 200);

while (Vm.getTimeStamp()  < (Vm.getTimeStamp() + 5000))
{
    spinner.update();
}

  //Spinner inside the ProgressBox
Spinner.spinnerType = Spinner.ANDROID;
ProgressBox pb = new ProgressBox("Alert!", “msg”, null);
