While we've gotta wait until Barcelona to see Samsung's Ultra Touch S8300 slider for ourselves, a handful of outlets have already played around with a preview unit, complete with the TouchWiz UI makeover.

Other than some of the icon graphics and the aforementioned menu updates, the UI is largely unchanged from its previous form. The lack of WiFi is gonna ruffle a few feathers, but the HSDPA will probably assuage some of that pain.
