Apple just revealed that it has sold 800 million iOS-powered devices, which includes iPod touch units, iPads and iPhones, to date.
By comparison, during WWDC 2013 last year, Apple announced that it had sold 600 million iOS devices. That means the company added 200 million iOS devices in just a year.
The breakdown is as follows: 100 million iPod touch units, 200 million iPad units and 500 million iPhone units. Amazing!
