A friend of mine is heading to Brazil for Carnival and didn't want to take his iPhone with him. Because he's on Verizon he would have to buy a unlocked phone which would have been kind of expensive for just this one week trip.
What I did because I'm on AT&T is buy the gophone from BestBuy for $2.99 on sale right now, then called AT&T and since my account is in good standing they gave me the unlock code. I then gave him the phone and he's on his way down there now. He'll buy a local SIM when he's down there. All you have to do is call AT&T customer service to get it unlocked.
Hope this helps you!
Cool thanks.. another choice
