iPhone 5 Design Images with Larger Edge-to-Edge Screen?
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.Chinese accessory manufacturers clearly get access to early design documents as has been evidenced multiple times. The early iPad 2 cases were indeed accurate representations of the iPad 2. iDealsChina was also the source of a design rendering of the 4th Generation iPod Nano which turned out to be an accurate depiction of the then-unreleased iPod Nano.
If this is indeed an accurate design document, we would expect to see accessory companies to start creating actual cases. We should warn that even if this is a real "design document", we've also seen cases for products that have never been released. The most notable is the iPhone Nano which saw several case designs from different manufacturers.
