Want to know the latest batch of next iPhone rumours? How about these-- bigger display handling more pixels, smaller Apple dock connector and iOS 6. 

If 9 to 5 Mac is correct, Apple has 2 prototypes at its HQ bearing the codenames N41AP (5.1) and N42AP (5.2), both housed in thick, locked shells to disguise them from curious, spying eyes. 

Both prototypes apparently carry a "new, larger display" measuring 3.9 inches diagonally with a 640x1136 resolution and 16:9 resolution. In contrast, all current iPhone models have a 3.5-inch display with a 3:2 aspect ratio, while the iPhone 4's Retina display handles 640x960 resolution. 

On the hardware side, 9 to 5 Mac says both prototypes still carry a home button, together with a narrower (between the size of a Micro- and Mini- USB port, apparently) dock connector. 

The software should also get upgrades-- an iOS 6 version custom-built for the bigger display, with a "tweaked" home screen and extended app UIs. 

The website promises it will have more rumours soon (including processor specs), but surely only Apple knows what is happening on the next-iPhone front...
