Martin Hajek has been busy this week: after iPhoneclub commissioned him to create concept images of an iPod Nano-inspired design of the iPhone 6, French site Nowhereelse asked him to use the Japanese sketches mentioned in that piece to create something far closer to the existing iPhone 5s design.

With many of our commentators criticizing the square corners of the previous concept, this latest one returns us to the rounded corners we know and love. More controversially, perhaps, we also see a return to the glass back. More images below the fold …

The design also returns us to the single rocker-style volume button we saw on early iPhones, rather than the two separate buttons seen on later ones.

Hajek has an interesting take on the gold iPhone, giving it a white casing with gold edging. We’ll be reading the comments with interest on that one.

As with the earlier concept, the thinness is probably not entirely realistic, but we can probably expect to see Apple shave a little off the depth of the phone as the larger form factor permits a thinner battery.

As we mentioned earlier, we’re far from convinced that the original sketches are real, but it’s certainly interesting to see renders of something that is probably somewhat closer to the real thing. As ever, let us know in the comments what you think.

Of course, there is still no shortage of silly concepts out there …
