Leaked Photos of Next Generation iPhone?

Images claiming to depict the back cover of an upcoming iPhone have started circulating on the internet. iPodObserver first posted a version of the above photo that allegedly depicts an unreleased 16GB iPhone with the model number A1303. This new iPhone case is said to "shed its glossy appearance for a matte black look" and also introduce a new case-back made of metal. The site seems confident in the photo and reminded readers that they were also responsible for publishing an early back-case photo of the iPhone 3G.

MacRumors has also received additional images (below) that appear to be from the same series. While we can't confirm their authenticity, we present them for discussion given iPodObserver's apparent belief in them. The images have reportedly come from China and are said to depict the back-casing of the next iPhone. The case is also said to be textured for better gripping.

The original iPhone came with aluminum back casing. This design eventually gave way to a smooth plastic curved back of the current iPhone 3G.
