I just updated my DHD to the official Sense 3 update.
Anyway, In Sense 2.1, I was using the sleek Slate skin. After updating, I went to "Personalize -> Skins" and chose "Get More"; Slate skin was not there. Also choosing different skins will produce "similar" looking skins (maybe with a little difference).
So, anyone knows how to get the old Slate skin back?
