Apple is significantly increasing the production of iPhones for the back half of 2011, most of which will be the iPhone 5, part suppliers divulged Monday. Volume was going up 12 to 13 percent to over 56 million phones, nearly half of which would be the iPhone 5. While it had trimmed back its iPhone 5 production for the summer down from seven million to no more than 6 million, Digitimes saw that it would more than compensate for this by surging orders in the fall from 14 million to 20 million.
