did some searching online but couldn't find anything. does anyone know if/how i can bring my iPhone with me on a trip to Cuba and get service for it while on the island? i am assuming i would need it unlocked and pick up coverage from a carrier while there. from what i've read, you need a gsm phone for any carrier there. i'm covered there, since i've got an AT&T iPhone 4. anyone have any information that could help me out? thanks!
