I am thinking of switching to ATT from t-mobile cause I want the iPhone and because I get bad service where I live and work with T-mobile... so my question is.. Can I just switch to ATT and get and of their free phone and then buy the iPhone the next day? I am just saying cause no matter what, you cant get a discount buying a Iphone....I am just curious cause I never seen a discussion regarding this and it would be nice to have a extra phone laying down if you ever need to send it to apple
