Whenever I download a full theme, not everything is complete, or most of it, I should say. I could enable a full wooden theme, and the background would turn wooden and the icons would lose their names. None of the icons change like in the Cydia screenshots, and there are no changes to the dock. I am using 4.0 on a 2G iPod touch. I made sure that everything included in the theme was enabled, and everything not included in the theme was disabled. What's wrong?
