yes, this one. different UI and keyboard layout. remade to great device, then remate again to cheaper device for developers

and yes, size was the same, but Beta2 had AMOLED and curved glass as on N9. also back side of sliding mechanism was more solid, like on E7. this what we have is like of plastics :-/ but it was changed on the last time to make it cheapier and fast to do. that's what I've been told.
