FedEx is the primary courier that Apple uses to deliver products sold through its store. Apple is an important customer for FedEx, and the delivery company just that he announced many employees that their vacations and departures are postponed in the interest of work due to a substantial increase in the volume of deliveries between September 21 and 24. Considering that then it is rumored that iPhone 5 is about to be launched, and considering that FexEx is the courier normally used by Apple, this increase seems to be due to the launch of the new terminal.
Although it is an indirect confirmation of the fact that iPhone 5 will be released then, FedEx is Apple's main delivery partner, it has been used in every iPhone/iPad release, so the information corroborates with each other.
