At last, some pretty credible parts apparently belonging to the iPhone 5S are starting to emerge. A set of images posted by a Chinese tech site and allegedly depicting the iPhone 5S parts on an assembly line include several shots of the device's internals, including a vibration motor that looks to be a linear oscillating vibrator like that of the iPhone 4S.
That would be a departure from the iPhone 5's more noisy rotational motor which uses counterweight. It wasn't immediately clear whether the leaked images are authentic or perhaps show an iPhone clone being assembled somewhere in China, though latter seems to be the case. I've included a few more snaps right past the fold...
