9to5mac reports that the code contains a reference to 'iPhone 5,1', seemingly an internal sign denoting the fifth iteration of the iPhone that is widely expected to launch next summer.
Previously, the developer code featured the 'iPhone 4,1', which turned out to be internal code for the iPhone 4S that was launched last month.
The code also contained two new references to the iPad, the first being 'iPad 3,3' - possibly confirming speculation that the third iteration of the iPad will launch next March.
However, the code also referred to the 'iPad 2,4', thought to be a slightly upgraded iPad 2 incorporating either next-generation Long Term Evolution technology, or WiMax. But it could also be the long-awaited 3G-only tablet for US mobile carrier Sprint.
It is thought that the iPhone 5 will boast a bigger four-inch screen and an aluminium casing.
Japanese technology website Macotakara.jp has reported that Hitachi and Sony are working on four-inch, LCD displays for a mystery Apple device, thought to be the iPhone 5.
The website's sources say that the new displays integrate IGZO (indium, gallium, zinc) technology and offer a pixel density of 330 dots per inch.
Separate reports indicate that iPad 3 will be 0.7mm thicker than previous models to include a twin light bar system.
The thicker size is said to be because Apple intends to fit the iPad 3 with a display running a 2048 x 1536 pixel resolution, a massive rise on the current 1024 x 768, and so requiring stronger back-lighting.
Meanwhile, speculation is mounting that Apple is working on a voice-controlled, web-connected TV set, after JVC was reportedly hired to begin commercial production on the product for a 2012 launch.
