Oh Goody We'll Be Able to Download at 2gps and still won't be able to get a signal in a area with multiple using the same service in the area. Oh, but you'll be able to download 20 times faster so you can hit your data cap in record speeds when you do get a signal. No thanks.
My money is on T-Mobile getting through more markets and better implemented. If you have kept track over the last couple years on what T-Mobile has been working on, their equipment and towers as well, impressive.
