Apple is expected to announce its next iPhone this fall, according to a report by the tech blog AllThingsD -- and this time, the smartphone is expected come with a companion.

Citing unnamed sources, AllThingsD reports that Apple is holding a press event on Sept. 10 to announce its next flagship smartphone, but did not give any more details on what may be revealed.

Apple is widely expected to unveil an update to the iPhone 5, which will likely be called the iPhone 5S, and a cheaper iPhone that many have dubbed the "iPhone 5C."

Few details are known about the next iPhone, except that it will come with a completely redesigned mobile operating system -- iOS 7. Other rumors suggest that Apple will include features like a fingerprint sensor, dual-LED flashlight and upgraded hardware. The new iPhone is also expected to keep the current design and 4-inch display.

Virtually nothing is known about the reported cheaper model that may be introduced with the next iPhone. Apple has yet to confirm that it is working on a low-cost iPhone. But photos have circulated of what could be the so-called iPhone 5C.

According to the tech blog Slashgear, a Vietnamese blog called Tinh Te leaked photos of what they claim are dummy models of the next iPhones. In one photo, the low-cost model appears to be the same size as the current iPhone, but made of plastic with slightly rounded edges.

In May, the Japanese blog Macotakara also said the cheaper iPhone would be made of plastic and claimed that the phone would come in a variety of colors, including navy, gold, gray, pink, green and orange.

Apple is also expected to officially launch iOS 7 and its desktop operating system Mavericks. Both were unveiled at the Worldwide Developers Conference in June.

Apple did not immediately respond to a request for comment.
