iOS devices are big business in China, and not just for Apple. Gangs of scalpers queue up to get their hands on the latest devices on launch day so that they can later be sold on through the grey market for a sizable profit.
Back in October, when the iPhone 4S launched in Hong Kong, police were called to break up the riots that occurred outside of Apple retail stores as scalpers attempted to force their way into the lines ahead of genuine customers. To ensure it doesn’t happen again, Apple has warned scalpers not to queue up for its new iPad on Friday.
