How do I get my iPod touch to change the locked screen wallpaper? I just got a new 2nd-generation iPod Touch 16GB. I believe I had a 2nd gen iPod Touch 8GB before.. but back when I did if I played a song, the album art would show up for that song on my locked screen. However this new iPod Touch doesn't do that (it just shows the default wallpaper I chose) and I can't seem to find the settings I need for it. Not looking for a jail-breaking solution by the way. Thanks.
Have you tried:


Select your iPod under the Devices section in the iTunes Source pane. 
Select the Music tab of the iPod settings. The iPod settings are displayed to the right in the main iTunes window.
Select the "Display album artwork on your iPod" checkbox.
Click Apply to save the changes. The iPod begins to update as soon as Apply is clicked.
