In a bid to keep iPhones sold in Hong Kong on the island nation, Apple has reintroduced reserve and pick up pages for the smartphones. The difference this time around is the inclusion of the customer's Hong Kong identity card number within the registration form, which goes live between 9am and 12pm each day. The aim is put breaks on the speculative smartphone buyers picking up several devices to mule across to mainland China. You'll still need a bit of luck; Apple performs a random draw each day for those that registered, and 'winners' are informed via email. Each card can apparently buy a limited quantity of the in-demand phone -- one that's getting some smartphone obsessives a little too hot under the collar.
