I will be in Spain, England, and Switzerland for almost two months starting in the beginning of June and I want to know my options. I have an AT&T 4S on 5.1. From what I see the Gevey Ultra S should work? I'm on baseband 2.0.10. Are there any other ways that are out or currently in development? Thanks. Also, does anyone have any recommendations on what local carriers to go with/plans/pay as you go while I'm in Europe/those countries?
