Apple will be launching its newest high-end smartphone this Fall, but the multi-million dollar company is still silent on some details.

Apple has not yet disclosed or gave an insight about what the newest smartphone will look like, but speculation and designer mock-ups are already all around the web.

The newest addition to the iPhone is rumored to be one of the most important and useful gadget in the brand's history and is said to be the most awaited Apple smartphone, according to Tech Radar.

The iPhone 6 will reportedly be released in September following the release dates of other iPhone's in the same month.

Apple is forbidding its employees to take their vacations in September, which suggests that it will be the month that the smartphone will be released, according to iFun.

Although Apple has not divulged any specific information about the iPhone 6, it is known that the new smartphone will have an iOS 8 operating system.

"iOS 8 is the biggest iOS release ever - for developers and everyone else. But that wasn't the goal. We simply set out to create the most natural experience. Each enhancement has a purpose. Every new feature deserves to be a new feature. Each function is more considered, each next step is more e?cient. It all adds up to an even better experience - one that is pleasantly surprising at ?rst and becomes utterly indispensable before you know it," Apple stated on its website.

Meanwhile, in China, it is reported that the iPhone 6 will be launched on September 15, but will not be available until ten days later, September 25.
