Okay, this is me. I am going to the U.S. for college, and all I want is an iPhone 5, with unlimited texting AND calling. I don't even mind having no data at all. I've gone throught all the contract ones, the unlocked ones, and I came across straight talk through a friend that lives in the U.S.. But I find it very confusing, after lots and lots of search, I cannot figure out what it IS, or how it's set up. Can I just buy a unlocked iPhone 5 from apple, then just buy a straight talk micro sim and BAM it will be there? How do I pay the $45 dollars a month? Why do I find so many people talking about AT&T straight talk, Verizon straight talk, Sprint straight talk. What's the difference? And my friend said the iPhone HAS to be AT&T for me to use straight talk, is it so? Thanks for answering all of those. Repeating, all I want is the best deal on an iPhone 5 with unlimited calling and texting.
