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.
IPhone 6
The iPhone 6 and iPhone 6 Plus were officially unveiled during a press event at the Flint Center for Performing Arts in Cupertino, California on September 9, 2014 and released on September 19, 2014; pre-orders began on September 12, 2014, with the iPhone 6 starting at US$649 and the iPhone 6 Plus starting at US$749. In China, where the iPhone 5c and 5s were the first models in the iPhone series to be released in the country on the same day as their international launch, Apple notified local wireless carriers that it would be unable to release the iPhone 6 and iPhone 6 Plus on the 19th because there were "details which are not ready"; local media reported that the devices had not yet been approved by the Ministry of Industry and Information Technology, and earlier in the year, a news report by state broadcaster China Central Television alleged that iPhone devices were a threat to national security because iOS 7's "frequent locations" function could expose "state secrets."
