I don't know, I've been waiting for Wimax in PR for 2 years know ... They said it would be up and running in a few months when I bought the original Evo. Know they are testing Wimax in PR Finally, LTE probably in another 2 years... But still I like Sprint and I will upgrade for the Evo LTE most likely.
I wasen't to far off, more than a year and a half from now anyways. But like I said I will stay with Sprint there customer Care is the best that I've experienced. 3G is not that bad plus I have Wifi at home.
