Apparently a Vodafone sales rep rang up the White iPhone 4 as a Black 16gb model in their point-of-sale system before the company told its employees not to sell units carrying the MC604B/A model number. The current UK 16gb Black iPhone 4 has a model number of MC603B/A, with the ‘4′ presumably representing the difference in color for that capacity.
