Terrain Dynamic lighting?

Hey everyone, i recently upgraded to unity 3 and i just saw that the option to switch from the terrain from lightmapped to vertex lit or pixel lit has been removed. I really need dynamic lighting on the terrain inorder to create a smooth day night cycle so is there any way i can get vertex lighting (or any dynamic lighting really) on the terrain again?

Now the dynamic lighting and shadows works on the terrain by default.

hmm i see that now. however i need to force it to not use a lightmap by setting the lightmapinxex to 255. thanks.
