Behold an iPhone 6 concept: All grown up (pictures)

Italian designer Federico Ciccarese has wowed us in the past with his concepts for an iWatch and iPhone Air. Recently, he got in touch again to share his vision of an iPhone 6 offered with larger displays, based on rumors that the next Apple phone could come in 4.7-inch and 5.5-inch models. In this image, he shows how the higher resolutions of such displays will free up room for more icons on the home screen.

Federico Ciccarese's concept for a larger iPhone 6 still maintains the thin, sleek profile that is rapidly becoming a trademark of all Apple products.

Looking at the larger iPhone 6 concept from the bottom up; notably, the headphone jack has been relocated from its current position on the iPhone 5S.
