Hi Suededevil, I am aware that my response is ten years overdue but I happen to be a Mormon, and this morning as i was studying my scriptures, I came across the word as used in 1 Nephi 20: 4 in the footnotes. It was not the first time I was encountering it but my interest was piqued because verse 4 describes the House of Israel as having their necks made of iron sinew and their brows being brass, which is explained in the footnotes as stiffnecked. additionally, the verse uses the term obstinate and so this is the meaning of stiffnecked. It has an element of stubbornness and foolish pride, as well as being unteachable. This makes more sense when understood from the concept of the Jews having rejected their redeeemer....
