    How exactly does the shape of the ice prevent it from melting? I call BS.

    Because heat loss is roughly proportional to surface area, and for the same volume a spheres area is about 20% less than that of a cube, hence you might get 20% longer out of your ice cube. In practice its going to be more complicated and the difference is probably pretty slim, cool though.
