This concept does seem to be inspired by a recently discovered Apple patent that shows an iPhone with wraparound curved display,.
In addition to the flexible display, this iPhone 6 concept has an iPhone 5c-like body with curved edges and corners, an iPhone 5s-like Touch ID fingerprint scanner, and would presumably offer an “all-new design, astonishing screen, better camera [and] higher performance.”
Apple is expected to unveil two iPhone 6 models this year, with at least one of them offering a larger display than predecessors. A recent report revealed that the first Apple phablet will have a design inspired by the iPhone 5c (when it comes to design lines,)and the seventh-generation iPod nano (when it comes to build quality).
We will love if they give a metal back like the first iPhone.
