Production of the so-called iPad mini is in progress at a Brazilian factory, says a source for Macotakara. The person doesn't name the manufacturer, but it would almost certainly be Foxconn, Apple's main supplier, which opened up a Brazilian plant just this year. Additionally the source claims that the production version of the new iPad is missing a microphone hole on the back, despite earlier mockups suggesting one, and the presence of a rear mic on the iPhone 5.
