As far as I'm aware, although our phones are now running Gingerbread, they are still running samsungs GalaxyS TouchWiz
launcher. The launcher is the app that controls your homescreens, wallpapers, menus etc... This means that your phone will still have the white menus etc.
If you really want the gingerbread launcher you can get it here:

Once installed, hit the "home screen" button and choose the new launcher (Not TWLauncher, thats the touchwiz one) and your away! Almost 100% default gingerbread!
