A mysterious Twitter user posted photos of the alleged iPhone 6 casing, which displayed a wider screen and a curved design.
The new set of photos is one in a series claiming to be the actual iPhone 6 design.
The user, mornray866, has not revealed the source of the images or explained why many of the phones are shown in plastic bags.
Apple has refused to comment on the details of the upcoming phone, though there are plenty of rumors to supplement its silence.
Some speculate that there will be three different models of the iPhone 6. The first will be a 4 inch 1136x640 (326 ppi) display for the cheapest iPhone. The second will be a 4.7 inch 1920x1080 (440ppi) display called the iPhone Air. The third will be a 5.5 inch 2272x1280 (510 ppi) display called the iPhone Pro.
The new iPhone will allegedly include a new camera module from Sony to improve the quality of pictures taken from its front facing camera.
The new phones are expected to be revealed at Apple’s annual developer conference in June, where the firm typically makes new product announcements.
If announced, the iPhone 6 is expected to go on sale within weeks of the conference.
