A friend from the U.S. wants to give me a gift of an iPad2 when he comes to visit in a few weeks. I live in France. He wants to buy me (and I want to own) the model with WiFi + 3G, which I gather requires choosing either the AT&T or the Verizon-compatible version. I am told (by someone who got a similar gift) that one of these versions allows you to install a foreign chip from my French phone carrier so I can get 3G locally, but this person didn't know which one. Can someone help so I can have my American buddy buy the right version to bring over. Thanks.
