According to French blog iGen.fr, the source claims Apple will begin selling the two devices to the public on September 19. The blog has predicted previous releases in the past, but looking at Apple's previous releases, it's safe to say the iPhone 6 duo would release next Friday. For example, the iPhone 5S and 5C were announced on September 10, 2013 and released ten days later on September 20th.
Apple has a tendency to release devices on the Friday 7-10 days after the unveiling, they can't keep us waiting forever. Both iPhone 6 models are rumored to have a complete redesign, upgraded camera, A8 processor, larger battery, and of course the juicy larger displays.
