Apple has begun selling Brazilian-made 8GB iPhone 4s in that country, reports say. Previously all iPhone 4 models were made in China, but units are now rolling off of Foxconn's Brazilian assembly lines. The switchover is actually believed to have happened several weeks ago, but gone largely unnoticed. At Apple's regional online store, the Brazilian-made black and white models are listed as MD128BR/A and MD198BR/A, respectively. Earlier Chinese-made equivalents for the area bore MD128BZ/A and MD198BZ/A identifiers.
