How can I do this? I am leaving for Rome in 2 weeks and my shiny new Verizon iPhone 5 is coming with me. As I understand it, the GSM portion of the phone is unlocked so I should be able to throw in a SIM from a European carrier and go to town, right? If so, I'd like to avoid having to track one down when I get there. Is there any way I can get the SIM here in the US sometime in the next two weeks and get it all setup and ready before I go? Thanks!
