WinterBoard Settings will add an option for WinterBoard in your stock iPhone Settings application. When selected, you have the option to turn on/off SpringBoard Only (which will apply WinterBoard themes to only your SpringBoard) and Debug (I’m not exactly sure what this setting would do). You can also view all your WinterBoard themes from the Settings option.

You have to "Add Sources" to you sources in Cydia repository for iPhone first in order to install WinterBoard Settings. At "Add" sections you have to enter this address, http://david.ashman.com/apt..If you not clear about this you can check out my post on how to add sources via Cydia.

Install WinterBoard Settings Via Cydia

Launch Cydia > Select “Sections” at haptic menu > Select “System” category > and Select “WinterBoard Settings” or you can tap “Search” in Cydia and type “WinterBoard Settings” > Select “install” button at the right top and confirm it to install.

Ultimately, you would no longer need to use the WinterBoard application itself, you could do everything through the WinterBoard Settings. When testings WinterBoard Settings, I found that the two applications (WinterBoard itself and WinterBoard Settings) override each other. For example, if you set a theme using the WinterBoard Settings and then you go in a choose a theme from WinterBoard itself…it will override the theme you chose using the WinterBoard Settings and vice versa.

I also found that the SpringBoard Only option seemed to work. It leaves anything that shows up on the SpringBoard (Wallpaper, Dock, StatusBar, Wifi icon…etc) activated but turns off the theme’s mods like calculator, dialer, sms…etc. It also leave the theme’s lock screen mods activated as well.
