The Sept 21 date has been widely speculated to be the official selling date of the iPhone 5 in the US and several other countries.

In the notice obtained by MacRumors, FedEx issued the following statement, "Due to the upcoming 'surge volume' event between Sep 21-24, this class has been postponed to the week of Nov 5-9 and you have automatically been moved to that class. If you are unable to attend the week of Nov 5-9, please send me an email and we'll remove you from the roster. Thank you for understanding.

MacRumors suggests that the message indicates the shipping company is limiting employee travel and training during this period in order to meet the high demand expected once the iPhone 5 is on sale.

FedEx is considered as Apple's primary shipping partner in the US, but has utilized UPS during the heavy demand season.

The iPhone 5 will debut on Sept. 12 at the Yerba Buena Center for the Arts in San Francisco at a 1p.m. EDT, where it is rumored to feature other upcoming Apple products, from an updated iPod and the iPad Mini.

What has been heavily rumored for the iPhone 5 are the following: 4-inch screen with Retina Display, aspect ratio of 16:9, 1GB RAM, an eight-megapixel rear-facing camera, a two-megapixel front-facing camera, running on the latest operating system iOS 6, battery capacity of 1140mAh with its life going eight hours for 3G users and 14 hours for 2G users, A5X dual-core processor, and an improved Siri voice assistant.
