With Mobile World Congress around the corner, Samsung is prepped to launch the latest version of its increasingly impressive, finger-friendly TouchWiz
UI. Already spotted on the Ultra Touch S8300 slider
, the interface has been fitted with new 3D-effects eye candy, enhanced haptic feedback, and new gesture and voice controls. A new widget dock allows you to more easily manage an increased variety of downloadable widgets while Samsung's new Photo Contact feature provides better integration of your photos and contacts with what appears to be face recognition technology. We'll know more after getting our hands on with the UI at WMC next week -- an event that's shaping up to be the biggest cellphone show in years.
