The Sept. 15th Apple event slated to unveil the iPhone 5 will be taking place nearly a year after the iPhone 4S had hit the stage. Several of the device's features have continued to be highly speculated, as millions of fans eagerly await the latest smartphone's reveal and its official release date announcement.

Unconfirmed rumors are pointing to a Sept. 21st release date. With Apple having sent out its official invitations to the San Francisco showcase on Wednesday, most do not have any doubts that the iPhone 5 will be revealed. The invitation even shows the date of the event with a large shadow bearing the number 5, which many believe is a reference to the iPhone 5.

In 2011 when the iPhone 4S was rolled out instead of the upcoming 5, many people had been disappointed. However, with the passing of the late Steve Jobs happening before the iPhone 5 release, many have felt compelled to obtain the latest and last device from the iconic tech figure.

Reuters reported that the new iPhone will have a 4-inch screen, which is an increase from its previous 3.5-inch model, first debuting in 2007. Analysts said that the display increase is Apple's response to Samsung's larger and competitive Android phones, which have surpassed iPhones in smartphone sales.

Images of the iPhone 5 show a new 8-pin dock connector that would overtake the previous 30-pin iOS connector. The processor is slated to be upgraded, but there is no guarantee that the front and rear-facing cameras will be.

According to Mac Rumors, Apple may release up to eight new devices in 2012 alone and KGI Securities' Ming Chi Kuo thinks that the tech company will end up selling 45 million iPhones in the last quarter of the year. That would mean eight million more than the same quarter in 2011.
