Apple is expected to unveil the iPhone 5S on September 10, but the device's name is still unconfirmed. What we know is only based on reports that the new handset will be refreshed version of the current flagship smartphone similar to the transition from the iPhone 4 to the 4S. However, it appears that Japanese wireless carrier KDDI may have inadvertently confirmed the name. The same issue recently occurred on Apple's Hungarian site.
The iPhone 5S is listed on a public page of the carrier's website, apparently confirming that Apple will follow the trend it set with the 3GS and 4S. It's possible that KDDI is simply following public opinion, but it's just as likely that Apple has shared the information with carriers who will sell the new iPhone ahead of its launch. A number of American carriers have reportedly barred employees from taking vacation from Sept. 20 to 22, suggesting that the highly-anticipated smartphone will launch at the beginning of that window.
Countless iPhone 5S leaks have us believing that the new smartphone will sport a bigger battery, faster processor and even a built-in fingerprint scanner in the home button. We also expect Apple to offer Gold/Champagne and Graphite colored handsets in addition to the classic white and black versions. We won't know anything for sure until Apple makes an official announcement, which is expected to take place on Sept. 10 with invitations likely going out next week on Sept. 4 should that be the date of the event.
