History of Apple Inc.
The first version of the iPhone became publicly available on June 29, 2007 in selected countries/markets. It was another 12 months before the iPhone 3G became available on July 11, 2008. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the U.S., Canada and major European countries on June 19. This 12-month iteration cycle has continued with the iPhone 4 model arriving in similar fashion in 2010, a Verizon model was released in February 2011, and a Sprint model in October 2011, shortly after Jobs' death.
IPhoneography
iPhoneography gained popularity with the constant improvement through generations of iPhone cameras. The first generation of iPhone was only equipped with a fixed-focus camera with no optical zoom or flash. As it evolved into the iPhone 3GS, the camera became more intelligent with autofocus, auto white balance and auto macro. The iPhone 4 was the first iPhone that could natively do high dynamic photography. The iPhone 4S and iPhone 5 were released with a panorama function available in the built-in camera app. The iPhone 6 and 6S further improved on functionality and performance, allowing more sophisticated manipulation and higher picture quality.
