The iPhone 5 is expected to be released soon and there is more and more proof showing that the expected release date of September 21 is not just a rumor. iPhone service provider, AT&T has called for a vacation blackout starting Sept. 21, so its employees will be around to deal with the iPhone madness that will ensue once it hits stores.

According to AT&T staff, employees have been given a vacation blackout from Sept. 21 through Sept. 30, meaning employees can't take a vacation during this time. This move seems to be done to prepare for the release of the new iPhone, which several sources have said will be released on Sept. 21. AT&T's vacation blackout move seems to be in preparation for a week that is sure to be busy if the long-awaited iPhone 5 comes out when expected.

AT&T isn't the only one calling for a vacation blackout. Verizon is also having a vacation blackout from Sept. 21 through Sept. 30, giving even further proof that the iPhone is set to be released during that time.

There has not been an official announcement about the release date from Apple as of yet, but it is expected that Apple will reveal the new iPhone at a special conference on Sept. 12 and they will announce the Sept. 21 release date.  It is expected that consumers will be able to pre-order the new iPhone after its reveal on Sept. 12. There are also rumors that an iPad mini will be revealed that day.

Last year, the iPhone 4S was announced on Oct. 4 and the device hit stores 10 days later on Oct. 14. According to the new iPhone 5 release date rumors, the phone would come out nine days after it is revealed.

Leaked photos of the iPhone have already hit the internet. The new iPhone is expected to have a slightly taller 4-inch screen and a smaller 9-pin dock connector instead of the common 30-pin design. Photos have also shown that the headphone jack will be on the bottom of the phone instead of the top.

Earlier this month, there were some rumors swirling around Twitter that the new iPhone could cost $800, but these rumors were not confirmed.
