Can I buy any of their phones, have them unlocked, and then buy a SIM card for the them in BA?
I read through the "SIM Card in Argentina" thread and couldn't find anything on taking specific phones (namely, smartphones) from the US. I'm looking at the iPhone and newer Blackberry models. It seems as though ALL phones don't work.
Thanks.

Is there a reason you don't buy one in Argentina? All of the phones you mention are available here. Here is a link to one

You need not enter a contract, pay as you go service is available and very reasonable prices. If you decide on purchasing one in the US make sure it is GSM 850 / 1900 or GSM 850 / 900 / 1800 / 1900. Having your phone unlocked here is a pretty easy process and normal charge would be anywhere from $40 (pesos) to $100 Pesos depending on where you have it done.
Hope this answers your question.
