Don't know if already known but i just saw this:
http://www.coindesk.com/mt-gox-astropay-faster-latin-america-transfers/Dear customers of MtGox in Latin America: we are proud to announce that MtGox now has partnered with AstroPay payments provider to perform quick and easy direct bank deposits from Argentina, Brazil, Chile, Colombia, Mexico, Peru and Uruguay.
The option to use AstroPay with Mt.Gox in Argentina was available for a few days, but was later removed. The service seems to be still working for Brazil, Chile, Colombia, Mexico, Peru and Uruguay, but not for Argentinas Bitcoin community.
