Unsurprisingly, Apple has remained tight-lipped about the future of the iPhone. And despite the slow trickle of news regarding phablet-sized devices and sapphire displays, we’ve yet to see any authentic hardware leaks up to this point. Instead, concepts have been tiding us over, and the latest from Ciccarese Design are just as sleek as the others we have covered in the past. Federico Ciccarese’s designs showcase both 4.7-inch and 5.5-inch models of the unannounced iPhone 6, complete with displays that reach the edge of the phone, curved backs similar to the LG G Flex and the return of the Touch ID fingerprint reader. Ciccarese has also stacked his mockups alongside an iPhone 5s in order to give a sense of scale. Check out the comparison below, and head to Ciccarese Design for the rest of the images.
