THE ALL NEW IPHONE 7 WHAT TO EXPECT

Apple usually keeps the same design for two generations of the iPhone (the 4 and 4s, say, or the 6 and 6s), before unveiling a physical redesign on the next update. We expect the iPhone 7 to be fundamentally different in look and design to the two generations of iPhone that precede it.

It's possible that Apple will use different materials to make the iPhone 7 more durable. Before the iPhone 6 and iPhone 6 Plus were unveiled there was speculation that Apple would use Sapphire glass for the display and Liquidmetal for the chassis, and two generations later Apple may be ready to unveil one or both of these upgrades.

First up is a truly remarkable set of designs that take a key element of theApple Watch design - the digital crown control - and transplants it on to the side of the iPhone. It's really far out there, in terms of plausibility, but a fascinating imaginative leap. What do you reckon?

Design student Marek Weidlich has also created an iPhone concept that takes inspiration from the Apple Watch, particularly when it comes to the OS.

We've also seen some beautiful concept renders from the artist Yasser Farahi. Here are some of Farahi's stunning designs:

If that's not enough for you, we're also starting to see concept images of the iPhone 8. (Yep, the iPhone 8. This is getting ridiculous.)

On the Behance website, designer Steel Drake has posted some images of what the iPhone 8 might look like when it arrives a few years from now. This concept of the iPhone 8 is entirely covered in glass apart from metal sides.
