Is this the low-cost iPhone (NASDAQ:AAPL)? Taiwanese custom phone maker Techdy has posted images of what it claims is the shell for a cheaper iPhone. As previously rumored (I, II, III), the phone is said to have a 4" display (same dimensions as the iPhone 5) and plastic chassis - Techdy adds the chassis "feels more sturdy" than those of Samsung's Galaxy phones (they also use plastic), and that it suggests the phone will have thinner bezels than the iPhone 5. No details about the phone's display resolution, camera image sensor, or CPU. (Piper's margin analysis)
