To clarify: A system dump is merely a copy of the /system partition on your phone, and because this is a dump from a Droid X, it will NOT work with any other phone out-of-the-box. This merely is a starting place for devs to pick up an apk and then modify and resign it so that it will work with a different phone.
Unless you luck out. In the goodies thread is a slideshow widget that came from another phone. I've been using it for a long time. Nice little app that flips through an assigned folder's images, letting you pick the folder and therefore the images. Up to 4 slideshows will fit on a desktop. I've got pets, kids, and travel.
