Apple's new iPhone 6 could have biggest initial production

The company is anticipating large demand for the so-called iPhone 6 as it will be available with screens measuring 4.7 and 5.5 inches diagonally, the report said, citing unnamed sources.
The 70 to 80 million units by Dec. 30 would be much more than the 50 to 60 million units last year for the iPhone 5S and 5C, which have 4-inch screens. The iPhone 4S has a 3.5-inch display.
Apple has asked component makers to get ready to turn out up to 120 million new iPhones by the end of the year to take into account a possible higher failure rate for displays, the report said.
