I am fixing to go from the Droid 1 to the Droid 2 Global and i'm really confused on how the global part works. I do travel out of the country 5 or 6 times a year so this is something that i need to understand. Do i have to do anything special to my phone to make it work when i travel outside the country. I have heard alot of talk about unlocking the phone but i dont understand what that means and if that is something that has to be done for it work outside the USA. Would someone please explain to me what i need to do to have phone service outside the USA and if unlocking the phone is something i have to do. Thanks...........
