Are bb & back button tilted in?

[phenomic]

I have the 8310 and i noticed today that my bb button and back buttons are tilted. The bb button to the right and the back one to the left. I never noticed this before. Is it supposed to be like this or did something happen to my phone? It sort of looks a bit awkward and they feel funny lately as well.

If this isn't right, how do i fix it?
