Have you ever wondered how much your spanking new iPhone 4 would cost to manufacture? According to iSuppli, Apple’s 16GB iPhone 4 includes components that cost as little as $187.51.

The most expensive thing in the iPhone 4 is the retina display screen, which supposedly costs Apple $28.50 per unit.

iPhone 4 Cost

When the iPhone 3GS came out last year, its estimated cost was $179. Since then, the price of components dropped and it is now estimated to cost $134.

Like Business Week notices, the estimate doesn’t include costs for items such as labor, shipping, advertising, software development, or patent licensing.
