Does the iPhone 5S have an official release date? Initial reports for the iPhone 5S said that the latest version of the Apple product would be released in September, but the German blog iFun is citing a credible source "to be taken seriously" and reporting that the iPhone S will be released to the market on September 6. The September 6 release date for the iPhone 5S is a few weeks earlier than many people were expecting, but will come as a welcome relief to those who simply need to have the iPhone 5S as soon it's released to the market.

If the iPhone 5S ends up being released on September 6, it will have a slightly earlier release date than previous iPhone products. The iPhone 5 was unveiled on September 12 and went on sale in the U.S. nine days later. The iPhone 4S was announced on October 4, 2011 and went on sale in the U.S. 10 days later.

The new iPhone 5S may also have some additional features that make it an upgrade from the previous iPhone. The blog iFun reported to expect "two new device types, and this doesn't mean two different color or memory variations." Many people are speculating this news to mean that the iPhone 5S could potentially be sold in two different screen sizes, which would be a first for Apple.

The Wall Street Journal reported last week that Apple is testing bigger screens for both the iPhone and the iPad; the iPhone 5 currently has a four-inch display. There have also been rumors for months that Apple is working on a cheaper rear casing made of plastic, which may be introduced in the new iPhone 5S. Tech expert Michael Kukielka said the new casing is thicker than the iPod touch, while still being a bit wider than and having the same four-inch display of the iPhone 5.

The iPhone 5S could also potentially be more integrated with vehicles and used both easily and safely while in the car. Apple CEO Tim Cook said in last week's earnings call for the company that "having something in the automobile is very, very important." Last month, the company announced iOS in the Car, which is a new way to integrate messages, maps, and iPhones more closely with new cars from over a dozen manufacturers.

"It's something that people want, and I think that Apple can do this in a unique way and better than anyone else," said cook. "So it's a key focus for us."
