You can also just look for qvga themes that will change the background/wallpaper and most change the colors of the start menu and buttons and menu boxes. Those are the simplest to install because all you do is download the cab file to your device and click on it and it will install. I suggest downloading the cab first and saving it, then exit your browser and click on the cab to install. Most of the time I recommend downloading to My Documents or Windows. Good Luck!
