Another iPhone 5 rumor has surfaced overnight and again it is emanating from a Chinese site that claims to have some engineering diagrams of the iPhone 5.

The images resemble the current iPhone 4 with the exception of the screen. The screen appears larger and takes up most of the front face with an extremely slim bezel. The images do resemble a previous leak of the front panel which many claimed were fake.

We just got what appears to be mold engineering drawings for iPhone 5. These would be used by case designers to create plastic, TPU, aluminum, silicone and leather cases. A while back we hear rumors that iPhone 5 would have a curved back but these images show iPhone 5 with the same form factor as iPhone 4 but with an edge to edge screen.

It is certainly not unusual for case manufacturers to receive information in advance of a new Apple product launch. We have recently seen iPad 2 information leaked in a similar way and turn out to be accurate.

We don’t know if this is real at this stage but the idea of a larger screen in a similar sized form factor is very appealing. There are a few more images after the break; take a look, then let us know what you think? Would you like a larger screen without a dramatic increase in the size of the device?
