Apple has said that consumers would have to wait until April next year for seeing the iPhone 4 in white colour. The black colour is not a disgrace to the phone either. It fits the bill exactly and lends a rich look to the phone. One of the best features in the design of the phone is that it has a profile size of just 0.37 inches, making it one of the slimmest phones in the market.
