When it arrives later this year, the iPhone 5 will be thinner, lighter and more complicated than ever for its manufacturer to assemble. That appears to be a takeaway for Apple generalists from The Wall Street Journal's new report trickling out details of the forthcoming smartphone. But the most revealing item in the report is the "complicated and difficult to assemble" refrain from the phone's manufacturers, which wouldn't be the first time we've heard a similar sentiment:

Hon Hai, based in Taiwan, is the world's biggest contract manufacturer of electronics by revenue and is the global assembler for Apple products. Two of the people, however, cautioned that shipments of the new iPhone could be delayed if Hon Hai can't improve its yield rate as the new iPhone is "complicated and difficult to assemble."
