I just switched 3 Iphones from At&t to T-mobile. The data sucks to far. I have searched all over and even called customer support for help. Will the Iphone be able to work on T-mobiles 3G/4G LTE towers? I live in North Carolina. I seen online a tower in jamestown, north carolina that was inspected on February 4, 2013 and thats about 10 minutes from me. Will that tower provide me with faster data? Does anyone really know?
