What Does iPhone 5 Mean?
The iPhone 5 is the sixth iteration of the ever-popular Apple brand of touchscreen-based smartphones. Although upon first impression the iPhone 5 is not very different from its predecessor, the iPhone 4S, it is actually lighter and slimmer and has a higher resolution "retina" display. Several other subtle changes can be seen at closer inspection of its external structure, like the height of the front glass protrusion and the bevels of the edges. It comes equipped with the iOS 6 operating system.
The iPhone 5 was officially announced on September 12, 2012, and was available for pre-order two days later. Apple received more than 2 million pre-orders, with pre-order totals selling 20 times faster than the iPhone's predecessors. The iPhone officially launched on the September 21st. As expected, demand for the product exceeded the supply available at launch.
