Recent update of Apple website indicates that iPhone X will be released in three new South American countries in early December. Those three countries are Colombia, Chile and Brazil. Smartphones will be available from select carriers and resellers. In case of Brazil, iPhone X will also be available from two Apple retail stores in Rio de Janeiro and São Paulo. Beware, though! Supply is said to be quite limited.
Brazilian iPhone X will cost 6999 reals, which is slightly over $2150. Very high price of the device (lets remember, US release of iPhone X costs $999) is due to the country's 60 percent duty on imported products, strict labor laws and more. iPhone X price in Chile and Colombia is currently unknown.
