You can use Dispersion in the standard_surface shader, yet I'd say it's not really the strength of Arnold (since it's a uni-directional path tracer).
You can use the JF Nested Dielectric shader (https://vimeo.com/86272108) hopefully soon with Arnold 5, currently this shader works only for Arnold 4.
