Anyone have a good example of using touch movement to rotate a 3D object around its center axis? I know I have to transform the angle based on the camera view matrix[...]

If you're happy doing matrix manipulation then it's cool but I'd recommend quaternions for rotations, I found them less of a headache. Not that it answers your touch issue though, sorry!
