Featured Image Meta Box

I am using custom press to create a custom post type and information about it. When a user is adding to that custom post type I want to move the featured image as the second option. I have moved it from the side using this code

add_action('do_meta_boxes', 'change_image_box');
function change_image_box()
{
    remove_meta_box( 'postimagediv', 'APPS', 'side' );
    add_meta_box('postimagediv', __('moved position'), 'post_thumbnail_meta_box', 'APPS', 'advanced', 'default');
}

However all attempts to get it to move to the top under the editor is not working. Any ideas?
