China Mobile ringing up sales for hotly anticipated iPhone 6

Try not to have a party before payday this month. You may need money earlier than you thought if you want to show off that new iPhone 6 to your colleagues.

On Tuesday, a week before Apple Inc is set to unveil its next-generation smartphone, China Mobile Ltd - the world's biggest telecom carrier by subscriber number - kicked off online preorders for the widely anticipated device.

China Mobile's preorder campaign also confirmed rumors that Apple will release larger screens for the device as buyers are asked to choose either a 4.7-inch version or a 5.5-inch one. The iPhone 5S has a 4-inch screen.
