Check out these two concepts: Apple iPhone Air, and Apple iPhone 6 Curve68
Italian designers SET Solution have produced a pair of concept iPhone models for your perusal. Besides the curved screen Apple iPhone 6c, the designers took the thin form factor from the new Apple iPad Air and applied it to an iPhone. The actual design cues for Apple's new full-sized slate come from the Apple iPad mini, and the result is a fabulously thin handset that alas, is nothing more than a pipe dream for now. The Apple iPhone Air concept is 3mm at the bottom and tapers down to 1.5mm on top and looks as though it would break if you just looked at it the wrong way. At 70 grams, it would weigh 38% less than the Apple iPhone 5s.
The Apple iPhone 6 Curve offers a dramatic curve, much less gentle than the one employed by LG with the LG G Flex. The buzz around the water cooler is that the new iPhone models will use glass that curves downward at the edges. Of course, we will never know for sure until Apple makes its annual introduction next year of the next-gen iPhone models, whether these early reports are true. In the meantime, you can check out the two concepts by clicking on the videos below.
