Another new device in the hands of other users means it going to get put through the inevitable system dump. That is exactly what has happened to the Motorola Atrix 4G and it has some goodies for everyone out there. Wallpapers, ringtones and even the boot animation are all available for download now.
Plus, if you like to tinker around with the internals you can get at the complete system dump as well. If you're not much for that, stick to the basics but if you're a developer or ROM cooker then by all means have at it. [Android Central Forums]
