The iPhone 5 will arrive on the carrier on December 14th.
Those pre-orders however are not backed by any kind of down payment, all that is required to pre-order the device is an ID card and a telephone number.
Interestingly, China’s and the world’s biggest carrier, China Mobile still does not offer the iPhone 5. If Cupertino secures a deal there it might get a huge opening. Even without China Mobile officially offering the iPhone, there are now over 15 million iPhones on it, much like there are on T-Mobile.
