In the Sprint TP manual (Page 16), it says the Navigation Control (dpad?) works Left and Right as well. (in addition to Top and Down)
But I am not able to get side ways navigation. (in portrait mode). There is nothing clickable to the left or right of the circular Enter/Ok button. Only the Top and Down of it is clickable and thus Top and Down works.
Does it work for you folks?
Is it a defect on my device?
EDIT: I figured it out. Was not pressing far enough to the sides!
