My sister has an iPhone 4 here in the U.S. She is going overseas to Italy for 3 weeks starting next week. She wants to be able to use the phone there, but is worried about it being really expensive. What's her best bet for being able to still have it over there to use? Should she jailbreak / unlock, or is there a better option to have a her account changed for the time she's there?
Thanks!
Thanks!
