     /private/var/root/Library/SummerBoard/Themes/
   • Firmware 1.1.3
     /private/var/mobile/Library/SummerBoard/Themes/
4. Launch “SMBpref” and turn ON  the following options:
   • Theme Wallpaper - ON
   • Theme Status Bar - ON
   • Theme Icons - ON
   • Theme Dock - ON
   • Wallpaper - ON
   • Skip Last Row - ON (for firmware 1.1.1 & 1.1.2 only)
5. Look for the Name of the theme you uploaded under “Themes”, and select it.
