A flyer released in China this week could have spilled the beans regarding the release of Apple's next smartphone device, the iPhone 6.

Based on the flyer, the 4.7-inch device will sell for roughly $851 in the U.S., while the 5.5-inch device will go for $1,012, according to GSMInsider, citing Phone Arena.

Apple is expected to announce its next iPhone sometime this September.

A Sept. 19 release date has been set for China, according to the flyer, which means a similar release should take place in the U.S. as well, along with a number of other countries.

Spigen, a U.S.-based case manufacturer, has listed a number of iPhone 6 cases in Amazon. The case can already be pre-ordered at this point, but the availability is set to Sept. 30.

Color options available include satin silver, smooth black and a gun metal case. Notably, Spigen has added cases only for 4.7-inches iPhone 6 variant so far.

A new scratch test reveals that the Sapphire crystal display may not be part of the 4.7-inch iPhone 6 devices as well.

A Taiwanese report released last week claims that the manufacturing process of 4.7-inch model will start in the third week of July and the 5.5-inch model will start in second week of August.

Usually Apple waits to release its new smartphone on a Friday, which means the iPhone 6 could become available for purchase on September 12th, 19th, or 26th.

Rumored specs for the next iPhone device include: 1704 x 960 pixel resolution, a faster A8 processor, a thinner profile, bezel-free design, camera upgrades, and a more durable, sapphire screen.

A new iOS 8 operating system that the next iPhone will utilize debuted at Apple's 2014 Worldwide Developers Conference earlier this month.
