It looks like Apple has started selling iPhone 4 units from Foxconn's new Brazilian manufacturing plant, which has been up and running since late 2011. According to photos released by Portuguese news site Meio Bit, the iPhone 4 handsets in question appear to be the lower-end 8GB models, with stamps indicating they may only be just a few weeks old.
Gizmodo Brazil previously took a few photos showing Foxconn's Brazil's production. In addition to producing the iPhone 4 in Brazil, Foxconn plans to build 5 more production facilities in the surrounding areas to help with growing demand for the iPad among consumers.
Since Brazil also imposes very high duties on iPhones and iPads imported from China, it's conceivable that switching to local production could eventually eliminate those fees and bring iPhone and iPad pricing more in line with other regions, making the devices more accessible to Brazilian markets. No such price reductions are evident yet, however, so there may be other factors involved that require additional time to sort out.
