They will be launching on 'leading' carriers in Argentina, Brazil, Colombia, Mexico and Peru. Which carriers in particular will carry the devices have not been announced.
Quote from Motorola Mobility:
“Latin America continues to be important to our company’s global strategy, which is why we’re bringing the region our most ground-breaking products,” said Maurizio Angelone, vice president and general manager Mobile Devices Latin America, Motorola Mobility. “We’ve received an exceptional response for Motorola XOOM and Motorola ATRIX from consumers and carriers in our U.S. and European markets, and we want to build the same excitement in Latin America.”
This is great news for consumers in any of the aforementioned countries who have been waiting patiently for the Xoom and the Atrix to come their way. [Motorola]
