According to investigation conducted by iSuppli , the iPhone4 16GB just costs under $ 188 which is definitely more than production cost of Droid and 3GS but is very low compared to the actual price quoted by Apple , most of the budget goes in the fancy retina display – the screen which is produced by LG costs $ 28.50 per unit . The A4 processor which is much emphasized in iPhone specs is a Samsung product and costs $ 10.75 , and the new gyroscope chip placed in the circuitry is estimated to cost around $ 2.60 .
So iPhone developers how much do you feel is Apple’s profit on each unit , iSuppli hasn’t taken in account the marketing , design , manufacturing , development , AT&T’s contribution etc costs . But of course iPhone4 is bigger deal for Apple than its previous models and also a great platform for which iPhone app developers can place their best iPhone application on the App Store .
