With Apple reportedly set to launch the iPhone 6 this September, the smartphone rumor-mill is alive and spinning again.

After designs for the next iPhone were leakedconcept designer Martin Hajek drew up these images of what the device could look like based on the diagrams. The phone is rumored to come in two sizes: both 4.7-inch and 5.5-inch models. 

Hajek's designs show up much slimmer iPhone, but with the same key features. If this does end up as the final design, what are your thoughts?

UPDATE: Newly leaked images allegedly show the back plate of the iPhone 6, straight from inside the factory.
