Has anyone heard anthing about Sprint possibly updating the EVO's EVDO Rev. A (i.e. 3G) up to Rev. B? It's said it will boost data speed's up to T-Mobile's so called 4G speeds. They say it can be done with just a software update to the phone. I hope they do. That would be a tremendous boost to those of us who have been waiting and waiting and waiting for WiMax.
