The iPhone 5 is a smartphone designed and marketed by Apple Inc. It is the sixth generation of the iPhone, succeeding the iPhone 4Sand preceding the iPhone 5S and iPhone 5C. Formally unveiled as part of a press event on September 12, 2012, it was released on September 21, 2012. The iPhone 5 is the first iPhone to be announced in September and setting a trend for subsequent iPhone releases, the first iPhone to be completely developed under the guidance of Tim Cook and the last iPhone to be overseen by Steve Jobs.
The iPhone 5 featured major design changes in comparison to its predecessor. These included an aluminum-based body which was thinner and lighter than previous models, a taller screen with a nearly 16:9 aspect ratio, the Apple A6 system-on-chip, LTE support, and Lightning, a new compact dock connector which replaced the 30-pin design used by previous iPhone models. This was the second Apple phone to include its new Sony-made 8 MP camera, which was first introduced on the iPhone 4S.
