Apple fans are itching for the imminent release date of Apple's next flagship phone dubbed iPhone 6 and there are proofs that the next iPhone is coming very soon.

A wide array of rumours claimed that Apple will release two smartphones this year: a full-fledged iPhone 6 and a low-cost smartphone widely known as iPhone 5S.

However, there are various clues that hinted that the next iPhone or iPhones are coming sooner than later. One of these proofs is the latest note from reliable analyst Ming-Chi Kuo of KGI Securities. Kuo proved to have correct predictions and analyses when it comes to Apple devices. According to his latest note, two Apple smartphones are coming later this year.

An iPhone 5 with plastic casing is bound to hit the market in early September along with iPad 5. However, the rumoured full-fledged iPhone is facing production delays and setbacks with the inclusion of various components. Thus, delaying its release to late September.

Aside from the new iOS 7, Apple's iPhone 6 is speculated to be powered by A7 quad core chip. It will include some features such as Near Field Communication, 13MP back camera and longer battery life. And just like its brother, iPad, it may have a large internal storage of up to 128GB.

Meanwhile, the cheaper iPhone 5S is expected to boast a 4-inch screen display, a dual core processor and an 8MP back camera all housed in a cheap plastic casing. However, based on Kuo's latest note, we can expect that the low cost iPhone may boast the features of iPhone 5.

However, we can still ignore the reasons listed below until Apple officially announced the release date of its devices.

iPhone 5 Deals and Discounts - iPhone 6 and iPhone 5S release date may come sooner than later as deals and discounts of iPhone 5 and 4S are now available left and right. More deals, promos and discounts are being offered to previous iPhones signalling the imminent release of iPhone 6.

For example, the iPhone 5's price has been slashed to just $145.99 upfront on a two-year T-Mobile contract. The iPhone 5 was available for $99 when it first launched in April, but this was raised to $149.99 in May, after the promotional period. AT&T offers 50 percent price cut to all of its smartphones not just the iPhone 5.

Petragon and Foxconn Hiring Spree - Reports claimed that Pegatron, the factory hired by Apple to manufacture the iPhone 6, is hiring forty thousand new workers to ensure that production can keep up with demand when it launches in the fall.

This is in conflict with the latest report from Wall Street Journal which claimed that Foxconn, a Chinese contract manufacturer that Apple has worked with previous devices, has gone on a hiring spree to get ready for the upcoming iPhone 5S or 6 production.

Components' Production - In line with the hiring spree, some of the components to be included in the next iPhone are reported to have begun production.

For example, images of ultra-sensitive touchscreen display courtesy of Sharp Corporation are now viral in the Web. Rumours stated that Apple plans to include screen display from Sharp after it terminated its contract with Samsung in making the displays for iPhone.

Apple New Patents - More and more patents are emerging as release date of the new iPhone nears. Not so long ago, Apple was granted of a new patent for edge-to-edge or seamless screen display heralding rumours that the next iPhone will include an edge-to-edge screen.

Now, Apple is granted a patent for an interesting dual-sensor imaging system. This system engages two different image sensors, designed to capture and compare two dissimilar versions of a picture. This is likely to remove most of the flaws that phone cameras tend to show.

Analysts' Predictions - An analyst claimed that iPad 5 and iPhone 5 with plastic casing are scheduled for launch in early September while the full-fledged iPhone 5S release date was pushed back to the end of the month.

According to the latest note of KGI Securities analyst Ming-Chi Kuo, the rumoured iPhone 5S is facing production delays and setbacks with the inclusion of various components . Thus, it could yield to a limited supply upon release date.
