When iPhone 4S was introduced approximately one year ago, not that many people realized what was perhaps the most crucial feature that differentiated the iPhone from the other mobile phones. It was not the easily breaking glass design, the dual core ARM Cortex-A9 or even the Retina display. It was the Bluetooth 4.0 that really made the iPhone 4S to standout from the competition. Even though the general public did not really see the difference between Bluetooth version 4.0 and its predecessors, the 4.0 included a totally new technology under the Bluetooth specification which allowed the creation of extremely energy efficient wireless accessories and gadgets.You might ask how this relates to the iPhone 5? Well, let me go though some facts and let you figure it out. Prior to releasing iPhone 4S, Apple joined the Executive Board of Bluetooth SIG. Coincidence, perhaps? Joining the board of the organization that controls the development of Bluetooth gives them capability of both monitoring the adaptation rate of the technology and to certain extent, steering the development of it. Apple has since released new iPad, MacBook Air, Mac Mini and MacBook Pro; all with Bluetooth 4.0 support. Now one year after the release of the iPhone 4S there are only couple of other mobile phones that support the latest Bluetooth version.
