At first an iPhone would come to mind as a cell phone that would be compatible with the visually impaired, but I've got to admit that designer Bruno Fosi makes a pretty good case (both meanings). Basically by working with iPhone applications that allow text to speech and moon type tactile feedback, Bruno created a case that is engraved with icon shaped holes corresponding on the multi touch screen to a modified home screen with all those functions. The blind can literally do anything on an iPhone (except for watch a movie I guess) that anyone else can do. 

The only catch is that this is still in the concept stag, but it's such a strong one I'd be shocked if some company didn't go forward with it.
