Well i have 4G a while already in Minnesota with t mobile and Sprint and even where I live in Wisconsin small town I get 4G with t mobile where people on att only get edge. Well and with Sprint I get 3G all the way until I hit Minnesota then it is 4G. SO I am glad slow and expensive att has 4G now. And tip u might wanna root ur inspire since out of the box att put a throttle on the i think either download or upload speeds.
