A screenshot allegedly showing the next iOS 8 running on the upcoming iPhone 6 has popped up online, revealing what Apple's new OS will look like.

Apple's next-generation iPhone 6 is one of the most highly-anticipated devices of this year and great things are expected with this launch. First of all, Apple is widely rumored to finally take the step toward a bigger screen with its new iPhone 6, which will reportedly come in two large-screen models - one with a 4.7-inch display and the other with an even bigger, 5.5- or 5.7-inch screen.

A screenshot of what seems to be iOS 8 running on the iPhone 6 has now surfaced online on Weibo (via RBMen), revealing what the new OS could look like on a bigger screen. While the current iPhone 5S has a 4-inch display and lists 4 icons in a row on the home screen, the screenshot below shows 5 icons in a row on the home screen, indicating that it could be the next iPhone 6 with more screen real estate.

Moreover, the original screenshot reportedly had a resolution of 1,600 x 966 pixels, which is not the resolution of the iPhone 5S nor the iPad. It may be the resolution of the upcoming iPhone 6, but it remains unconfirmed at this point.

The leaked screenshot further shows a number of Apple stock apps that are already known, as well as several new ones such as iTunes Radio, Healthbook, and CarPlay. This falls in line with previous rumors that iOS 8 will introduce new apps and functionality. Several other Apple apps that are not pre-installed on the current iPhone 5S appear here as well, including Keynote, Pages, Numbers, iPhoto, Garage Band, and others. Meanwhile, other recently leaked apps such as TextEdit, Preview, and Tips don't appear in this screenshot.

In addition to a larger display, Apple's next-generation iPhone 6 is further expected to rock a new Apple A8 processor under the hood, most likely the company's new 64-bit powerhouse.

At least one iPhone 6 model is expected to launch in September, alongside Apple's next iOS 8 mobile operating system and the company's much-rumored iWatch wearable gadget. Rumors indicated that the smaller 4.7-inch model will launch first, while the larger model will debut later on.

Nothing is official at this point, so it is highly advisable to take all leaks, rumors, and speculation with a grain of salt for now. We'll keep you up to date as soon as we hear more.
