A new unofficial source has confirmed the existence of the iPhone 5S and iPhone 6, and while the source isn't really of the reputable type, we can't ignore it just like that. Here's how the story goes: a Chinese blogger from the site Sina Tech claims that a friend of his, who works at one of Apple's suppliers, has seen the two new iPhones. According to the blogger's friend, the iPhone 5S will look just like the current iPhone 5, but will feature some upgrades under the hood, including a new A7 processor. The iPhone 6, on the other hand, is said to be thinner, longer and wider compared to the iPhone 5. Apparently, the increased height and width signify the presence of an even larger screen, with the source claiming that the size will be 5 inches. This is where we should note that while we would believe that Apple might use a slightly bigger screen for the iPhone 6, a size of 5 inches sounds absolutely unthinkable for a company which is focused mainly on the mainstream market. However, it might be possible that the iPhone 5S will remain Apple's mainstream iPhone, while this new iPhone 6 model will be the phablet model, or the above-mentioned iPhone Math, though with such thoughts we're easily entering the area of wild speculations.
Apple increased the size of the iPhone screen for the first time with last year's iPhone 5, bumping it from 3.5 to 4 inches. While this display size is still much smaller compared to most models powered by Android OS, that is seen as beneficial to most Apple customers who often demand a highly-functional, but still compact and easy to handle smartphone. However, with mobile devices gaining access to more and more computational power, software developers have started creating more advanced applications like complex productivity tools and beautiful 3D games, not to mention interactive books and magazines. Naturally, such kind of applications would be experienced much better on larger screens, which is why we're willing to believe that Apple may increase the size of its iPhone once more with some of the future releases.
