An image provided by an iPhone case supplier suggests that the next-generation iPhone will have a wider Home button, larger screen and a newly-positioned flash for the camera.

Stuff reports that Fonegadgets has provided the picture of an 'iPhone Pro' case which shows a significantly larger screen and an elongated Home button, which could potentiall support left- and right-swiping gestures.

The camera's flash also looks to have moved, which Stuff speculates could reduce red-eye and improve image lighting qualities.

Fonegadgets is the same Essex-based supplier that provided Stuff with evidence that the next-generation iPhone would have a larger screen, curved edges, and a thinner, tapered, tear-drop like design in the form of claimed iPhone 5 cases last week.

Other iPhone 5 case designs have leaked in recent days - Chinese supplier Case-Mate published a page showing six case designs for the upcoming iPhone 5 last week but later pulled the images from the site.

As for the elongated Home button, some leaked screen protectors spotted last week seem to support this theory, though earlier last week supposed iPhone 5 components discovered by the How To Arena website seemed to show that the Home button would be similar to that on the iPhone 4.
