An analyst claimed that that the iPhone 6 and iPhone 5S will be released in September as the company started placing orders for the devices' components and production will commence in August.

Chris Whitmore of Deutsche Bank Equity Research said in his investors note released yesterday that Apple has placed long term requests; expects production in August for late September launch.

"Our checks indicate orders for the new iPhone are starting now for longer lead-time components. Specifically, we believe Apple is currently placing component orders for iPhone volume manufacturing to ramp in the August timeframe, suggesting they're on pace for a late September launch," Whitmore said.

He also dismissed the idea that Apple would be launching or unveiling any iOS hardware at next week's WWDC. "We don't anticipate any meaningful iOS hardware announcements at WWDC," he said.

However, he did join the chorus of analysts that say a redesign of iOS is coming this year. "We believe iOS is due for a material upgrade in order to freshen and reinvigorate the 'cool' factor around Apple's products. The general look and feel of iOS is six years old and is in need of an update and some spark. It seems clear that Jony Ive's fingerprints will be all over iOS7, which we expect to be the most significant iOS upgrade from a visual perspective."

According to rumours, iPhone 6 will come with a larger screen with the size of 4.8 inches. The screen display is speculated to be Retina+ with double the pixels compared to iPhone 5. There are also speculations that iPhone 6's new screen will be Sharp's IGZO display with 1080 HD resolution.

Some sources claimed that the iPhone 6 will feature a 3D technology. It will sport a 13 megapixels 3D rear camera and 3.2 megapixels HD front camera.

Rumour has it that Apple's iPhone 6 will be powered by A7 quad core processor, which claimed to be faster than the previous processor. The processor will be paired with iOS 7 operating system, which is packed with new and better features.

Apple may have planned to bump the storage capacity of its smartphones. iPhone 6 is said to be coming in 16GB, 32GB, 64GB, 128GB variants.

Concept images claimed that iPhone 6 will be packed with security features. It is reported that Apple is planning to include a fingerprint sensor in Apple devices for added security. Moreover, a new approved patent from Apple will enable users to operate their devices with mere scratches or tap gesturing.

The patent discusses acoustic input devices and basically means that iOS devices could also be used with sound inputs that would be transmitted via the casing that would then correspond with certain functions.

Lastly, a new concept of iPhone is making the rounds showing the device capable of wireless charging. One of the most common complaints with Apple devices like iPhone is the fast depleting battery. However, with wireless charging, users will enjoy longer battery life.

The rumoured low cost iPhone, on the other hand, is speculated to feature the same sleek design but with a plastic body. It is reported that the iPhone 5S will have some of the specs and features of iPhone 4S. The smartphone is alleged to be available in different colors.
