The new iPhone has not even yet announced, but there are estimates of its future popularity. Analyst Horace Dediu (Horace Dediu) of Asymco called fantastic figure of 250 million. Of course, this is not about sales for the quarter or year, and about possible sales of all-time production. However, his calculation is based on approval of the head of marketing Phil Schiller of Apple (Phil Schiller), who stated that "each new generation [iPhone] is sold to the tune of the respective total sales of all previous". However, this statement is not certain. It corresponds exactly to the consideration of the situation with the iPhone 3G, 3GS and 4, but in the case of the 4S is only partly true. iPhone 3G has sold four times larger than the original model. iPhone 3GS surpassed them both about 1.6 times, while the iPhone 4 three times exceeded the previous total. But the iPhone 4S is still on sale and still the leader, but to date he does not beat the amount of sales predecessors - the first four models differed in the two times in large numbers. Sales are continuing and will continue even when the new flagship will be presented. It is impossible to estimate how much will remain popular inevitably cheapened iPhone 4S after the release of the iPhone 5, but a chance to catch up and surpass the sales he has. In this case, the rule of Phil Schiller to be true and can really be expected to sell 250 million iPhone, which will be announced September 12, 2012.
