Over the past few months, we have seen numerous iPhone 6 mockups, dummies, front panels, displays, and a myriad of other things. As the release date approaches, we are likely to see many more concept designs and mockups surfacing on the web. However, earlier this week Japanese newspaper Nikkei said that the mockups have omitted many key details of the upcoming smartphone, which is expected to be released in September.

The neatest iPhone 6 mockup

Based on recent reports and leaks, designer Mark Pelin (via 9to5Mac) has created a set of the iPhone 6 images, which could well be the neatest and most accurate yet. It shows physical design of the 4.7-inch and 5.5-inch iPhone phones in space gray color. Pelin has devoted special attention to the smartphone’s all-aluminum rear shell. It has usual design changes such as the relocation of power button.

As you can see in the images, Pelin’s mockup maintains antenna breaks on the back of the device, while removing the glass sections found in the current iPhone 5S. That’s in line with previous reports. It uses black antenna breaks. The iPhone 6 is expected to feature a sapphire glass display and an upgraded A8 processor. It will also have an improved camera with Optical Image Stabilization feature.

Chinese carriers have started field testing the iPhone 6

Many reports, including the one coming from German carrier Deutsche Telekom, point to a September 19 release of the iPhone 6. However, latest reports coming from China claim that Apple Inc. (NASDAQ:AAPL) will unveil the device on September 15, which falls on Monday. It will officially go on sale on September 25, which falls on Thursday. These release dates look a bit fishy. Apple usually launches its new iPhones on a Friday to capitalize on the weekend crowd.

The Chinese report also claimed that the bigger 5.5-inch iPhone 6 will be named “iPhone Air.” Given its market size, China will be one of the first countries to receive the new iPhone 6 model. The report further said that China Unicom and China Mobile have already started field testing the iPhone 6 on their networks. Chinese companies are aggressively rolling out 4G networks across the country.
