Apple will sell its one billionth iPhone this year29
Unless the 4-inch Apple iPhone SEsuddenly reverses course and takes off, Apple will sell its one billionth iPhone in July, around three months before the Apple iPhone 7 and Apple iPhone 7 Plus make an appearance. To be more precise, Wall Street analysts are betting that the one billionth iPhone gets rung up on July 20th. It should be pointed out that Apple sold its one billionth iOS device in November 2014. That includes the iPhone, iPad and iPod touch.
The OG Apple iPhone sold 270,000 units in its first two days and sales hit the 1 million mark by September 2007. The Apple iPhone 3G sold one million units during its opening weekend, a number that shocked industry analysts. Compare that with the 13 million Apple iPhone 6s and Apple iPhone 6s Plus models that were sold during last September's opening weekend. With growth like that, you can understand why half of all iPhones sold were purchased just in the last two years.
