The iFrenzy is almost upon us. Apple has reportedly filed its largest-ever order of new iPhones, between 70 to 80 million units. Production is rumored to start in August for two models, a 4.7-inch screen and a 5.5-inch screen. For last year’s 5S and 5C release, Apple ordered between 50 and 60 million units, and struggled with shortages and long waiting lists. The upcoming phone, expected to be called the iPhone 6, could have a rounder body, tougher screen, better camera, and built-in barometer.
