Its hard to go a day without hearing a new iPhone 6 rumor, but todays (July 3) report out of China are among the more tantalizing, if not a bit hard to believe. China.com claims that Apple has set a firm Sept. 25 release date for the 4.7-inch iPhone 6, which will be followed by a 5.5-inch model dubbed the iPhone Air later in the year. The biggest hole in this rumor is that Sept. 25 is a Thursday, and Apple historically releases new iPhone models on Fridays.
