iPhone 5 cases are already being manufactured by retailers, including Amazon, who are preparing for those iPhone 5 fans who will be the first to purchase the Apple smartphone. Amazon is currently selling flip folio cases for $9.99 online. As the iPhone 5 requires a new cable connector, retailers are rushing to design new docks and other accessories to provide as Apple fans purchase phones on Sept. 21. 

As iPhone 5 cases provide an extra expense for customers, Examiner reports that Apple will earn at least $100 million on new cable connectors alone. Other retailers, of course will take advantage of the new sales opportunity to provide power adapters, dock connectors, and specialty cases. Popular brands including Speck and OtterBox are already preparing to deliver new cases upon the iPhone 5 release date. 

As rumors have indicated, the iPhone 5 is taller, thinner and with a tougher exterior. The bigger display makes the iPhone screen 4 inches across, 326 pixels per inch, and 1136 x 640 retina display.

The new gadget also features 4G LTE and a faster processor, Apple A6. And will operate on the new, iOS 6 which also comes with 200 new additions to the software, including turn-by-turn navigation and 3D mapping.

Apple Inc. have strategized to release upgrades only once a year for a product that makes up about 70 percent of the company's profit, according to New York Metro. Chief Executive Officer, Tim Cook, made the announcement about the new phone on Wednesday. You can also see the event on CNET's live blog.

A iPad Mini is the next thing on the list for Apple. It is said to come out October 2012 and Cook said "the iPad is driving the post-PC revolution at a breathtaking pace."

The Apple site called the iPhone 5 "The biggest thing to happen to iPhone since iPhone" and sales are expected to highly boost their current numbers. The only competition they might face, if any, is from Samsung, who recently released the Galaxy S3. Reportedly, it is said to bring in more than 30 million by the end of the year. The Galaxy Note 2 will also hit U.S. stores later this year.
