Check out these awesome Apple iPhone Air and iPhone Curve concepts

Although these two concepts of the Apple iPhone Air and iPhone Curve might never see the light of day, they are great to look at. These concepts are the work of Italian design firm SET Solutions. The iPhone Air concept focuses on rajor thin profile while the iPhone Curve uses a curved display, which we all know Apple just patented recently. The Samsung Galaxy Round and the LG G Flex have already made headway as proof-of-concept smartphones, but curved and/or flexible displays have yet to go mainstream.

The iPhone Air concept uses the iPad Air as reference for the design with a thin profile which is just 3mm at the base and 1.5mm at the top of the device. More than anything else, physics will play a spoil sport in creating such thin devices where you would have to incorporate a  humongous camera sensor and battery, which would not be able to fit.

The iPhone Curve focuses on colors quite like the iPhone 5C, and uses a more defined curve while the back remains almost flat.
