Apple will unveil new iPhones on September 12.

Apple will show off new iPhone models and other product updates come Tuesday September 12. the event will be held at the spaceship-shaped Steve Jobs Theater on its new Cupertino, California headquarters, expected to open later this year.

Apple will mark their 10-year anniversary of the iPhone this year and rumors indicate the company will introduce three new devices at the event: the iPhone 7S, iPhone 7S Plus and the so-called iPhone 8, which will be the 10th anniversary edition.

Although the launch event is slated for September, it may take a while for customers to get their hands on a new iPhone. Some analysts believe the anniversary device could be in short supply, citing "constrained supplies."
