Hi everyone. I believe I have a unique situation to ask about related to buying an iPhone. I'm from the United States, currently living in Brazil. I'm going back to the United States in a few months and I'd like to have an iPhone when I go back - especially since I'll need to maps application when I arrive in New York City. Anyway, my father lives in the U.S. and is currently eligible to renew his contract with AT&T. Therefore, he could purchase a new iPhone 3GS at the lowest price. In theory, I would like him to purchase the iPhone on his account, then send it to me so I can unlock it, use it in Brazil, then switch it back to AT&T once I get back to the States. So here's my question to you guys and gals... After my dad buys the iPhone, is there a way I can have him put his SIM chip back into his old phone and not have to continue paying the big data fees after he sends the phone to me, and then just have him re-start the fees once I get back into the U.S.? Please let me know what you know about this, and feel free to ask me any questions if what I've described so far doesn't make any sense. Thanks and peace and happiness to you all!
