Apple is expected to unveil three new phones at its live event - a 4.7-inch iPhone 7s, a 5.5-inch iPhone 7s Plus and a 5.8-inch iPhone 8. The iPhone 8 will feature an edge-to-edge display, so although the screen area will be bigger, the phone itself could actually be smaller than the iPhone 7s Plus. This mockup image, first shared by iDrop news, shows (L-R) the iPhone 7s, iPhone 8 and iPhone 7s Plus.

Pictures allegedly showing a dummy model of the iPhone alongside existing iPhones have been leaked by Carved Blog. They show the sleek new iPhone 8 next to existing Apple handsets, an iPhone 6s and iPhone 7 Plus. As can be seen, the new iPhone dramatically enlarges the screen so that it takes up almost the entire front of the phone. The famous Home button will be replaced either with a virtual one built into the screen, or another physical button on the side of the phone.

Apple has made a few other changes elsewhere as well. The camera lenses are now vertical when the phone is held in portrait mode - indicating that for best results it should be held in landscape mode.

The pictures also confirm that Apple will keeping its Lightning connector at the bottom of the phone - and that there's no return of the 3.5mm headphone jack.

While many of the mockups show a silver metal rim, this is expected to be colored to match the device.

The sleek device appears to echo the Samsung Galaxy S8 in making the display cover as much of the front as possible. However, it doesn't appear to curve around the edges of the handset in the same way as Samsung's phone. According to the pictures, the famous circular Apple Home button has been moved onto the screen itself.

These new pictures also seem to confirm the rumour that Apple will be moving the dual-lenses from running horizontally across the back to vertically when the phone is in portrait mode.

Accessory makers are sometimes given a sneak peek at new smartphones before they're revealed to the public. And if not, they can sometimes be given dimensions for mocking up their own renders . This means they can design cases that will be available to buy the minute the new gadget becomes available. One case maker has leaked what are believed to be accurate renders of Apple's next device. Posted on the SlashLeaks tech website, the pictures give us a good idea of what to expect when the iPhone 8 is revealed.

The iPhone 8 dummy was also pictured alongside an iPhone 5s, for scale.

Pictures shared on popular Chinese microblogging site Weibo also show what appears to be Apple's forthcoming iPhone 8 in three colours - white, jet black and a new colour, described then as a "champagne gold". Chinese website MyDrivers , which first shared the images, said the gold option was "closer to copper" in color.

It is not clear whether the devices pictured were taken directly from the supply chain, or if they are dummy models made by non-Apple suppliers based on recent rumours.

Apple's iPhone 8 could come in a striking copper colour known as "blush gold", if new leaked photos are to be believed. The pictures, shared on Twitter by prolific leaker Benjamin Geskin, allegedly come straight from Chinese iPhone manufacturer Foxconn. The pictures provide more evidence that Apple is planning to replace its "rose gold" colour variant with a more rusty, copper-like colour. The name "blush gold" is what Foxconn staff re using internally, according to Geskin.

More images show the iPhone 8 in a folding, wallet-style case. It clearly shows the silver trim around the sides of the phone and the lack (again) of a 3.5mm analogue audio jack. There are also dual speakers on the bottom of the phone.

Leaked images published on SlashLeaks appear to show computer-assisted design (CAD) schematics of the new iPhone. The pictures appear to confirm a long-held belief about the iPhone 8 - that the entire front of the phone will be made up of the screen.

In the dummy case pictures, there doesn't appear to be any space on the back for a fingerprint scanner. This could mean that Apple is planning to build the TouchID scanner directly into the front screen. What we can see is a vertical two-lens camera, which appears to have been carried over from the iPhone 7 Plus.

71mm in width.

Frequent Weibo leaker KK has shared renderings of what appears to be an iPhone 8 with a curved screen that covers the entire front of the device. An accompanying dimensional drawing shows that the bezel around the edge of the display is only 4mm thick, with the curved glass on either side of the screen accounting for 2.577mm of that width.

Following several rumoured design leaks and alleged pictures of the iPhone X, gadget watcher Steve Hemmerstoffer and Tiger Mobiles have created what they believe is an accurate dummy phone showing what it could be like. Shared on Twitter by @onleaks, the dummy shows an all-glass front and back and a vertical dual camera lenses on the rear.

The pictures are of a "dummy" iPhone 8 were created using a computer-controlled cutting machine known as a CNC router, based on leaked diagrams. The body of the device consists of "2.5D curved glass" front and back panels. It has a stainless steel band around the edge, binding the glass sides together. The power and volume buttons and the mute switch are all positioned along this band - in roughly the same locations as on the iPhone 7. The Home button has been removed, and the back of the device shows a dual-lens camera module positioned vertically, so that one lens is above the other, with a flash in between.

The device itself measures 137.54 x 67.54 mm, which is roughly the same size as the iPhone 7 , but the screen is 5.768 inches diagonally - almost identical to the Samsung Galaxy S8. This suggests that it might share the Galaxy S8's unusual 18.5:9 aspect ratio, although the images do not confirm this.

Steve Hemmerstoffer, who uses the handle @onleaks , posted this picture of what appears to be a dummy unit of the next iPhone. The pictures show a shiny reflective casing that could indicate Apple will continue offering the "jet black" colour that debuted with the iPhone 7. Likewise, Apple appears to have swapped the dual lenses from a horizontal position to a vertical one.

McDonald apparently leaked the design of the iPhone 8 in a promotional email was sent out to customers in Australia. The picture clearly shows a handset with a larger full-front display with a notch left at the top for the front-facing camera, earpiece and sensors.

The pictures a also show a narrow earpiece at the top of the screen, with the selfie camera, microphone and other sensors on either side. The renderings suggest that these components will all be concealed below the glass, although it is unclear how this would work in reality.

These renders are based on computer assisted design (CAD) files obtained by tech journalist Gordon Kelly working with case designer Nodus . Citing information from Apple's supply chain, Kelly has worked up some pretty impressive renders showing just what the iPhone 8 will look like.

These renders show the hotly-anticipated new gadget from all angles and seem to confirm a number of rumours surrounding the device. Most importantly, Apple is following Samsung's lead by dramatically enlarging the screen so that it takes up almost the entire front of the phone. The famous Home button will be replaced either with a virtual one built into the screen, or another physical button on the side of the phone. Like the Sony Xperia XZ Premium, this could be made to incorporate a TouchID scanner.

Apple has made a few other changes elsewhere as well. The camera lenses are now vertical when the phone is held in portrait mode - indicating that for best results it should be held in landscape mode. Kelly also believes the iPhone 8 will be sticking with the Lightning connector port rather than making the move to USB-C like Apple's Macbook range.

The iPhone 8 is expected to be the first Apple gadget to feature wireless charging. These pictures of charging pads have been circulating on Chinese social media site Weibo.

Although the charging pads appear to have been developed for the iPhone 8, there is a suggestion they will work with the iPhone 7s and 7s Plus as well.
