Analyst: iPhone 5S Will Have Larger Camera, New Fingerprint Technology, Same Screen Size
He claims the left side volume and mute buttons will be arranged differently, in line with a parts leak from yesterday, and says the rumored fingerprint technology will be the differentiating feature for the 5S, like what Siri was to the 4S.
White also shares some additional thoughts about the rumored cheaper iPhone he expects this summer:
Strangely enough, the lower-priced iPhone is still being called the "iPhone mini"; however, the general consensus (albeit a few disagreed and expect a slightly smaller screen) was that this new device would actually have the same screen size (i.e., 4-inches) as the iPhone 5. However, the "iPhone mini" will have a curved back casing made of colored plastic and will be thicker than the iPhone 5. We also learned the pricing could be a bit higher than our recently raised expectation, reaching as high as $400.The picture around this summer's iPhone releases should continue to come into focus as we see more hardware leaks and get closer to the expected launch.
