The wearable iPhone
This bizarre device is a kind of clip-on iPhone designed by Federico Ciccarese at CiccareseDesign. It looks like it might get a bit uncomfortable after a while but you’re certainly not going to drop it.

The ultra-slim iPhone
This beautiful concept by Antonio De Rosa of ADR Studio looks like a conceivable iPhone of the future (although not one slated for a September launch). It even comes in a variety of colours.

The transparent screen
This incredible concept phone was created by US teen whizz-kid Dakota Adney. Images are beamed onto the phone’s transparent screen. It isn’t very practical but it is very cool.

OK, so this one isn’t actually a design for an iPhone, it’s a concept design by Ciccarese for Google’s augmented reality hardware. With a bit of tweaking, though, this could be an awesome iPhone concept.
