Sources have told AllThingsD to keep Tuesday, September 10 open for Apple's next big media event. The company is expected to reveal both the iPhone 5S and a lower-cost smartphone known as the iPhone 5C. Judging from past events, iOS 7 will likely be released for all users around the same time, ahead of the ship date for new iPhone models.
As September 10 approaches, rumors will continue to surface with scheduled event dates at the Moscone Center as well as upcoming vacation blackout dates for Apple employees falling under scrutiny. Although parts have yet to surface, a redesigned sapphire home button including fingerprint sensor technology is a feature reportedly coming to the iPhone 5S, which would undoubtedly steal the show at Apple's event.
