I recently got my iPhone 5 for Christmas, and it's just now the beginning of April . It's always said 3G , instead of 4g , which I thought was normal . I was with a couple of friends yesterday, and she had a white iPhone 5 just as me, except she had AT&T and hers said 4g. I have sprint. Is there a way to get 4g? Does it cost money to have 4g? Everywhere I have went with no wifi it has always said 3G, never 4g. I want 4g though!
