Sprint is actually CAPPING their WiMax speeds at the moment, that may be to help them with overall bandwidth capacity until the network is built out, or not. Who knows....
I hear you about the customer service, so it's a hit or miss. The one you definitely want to stay away from is AT&T.....ouch. CS....more like, lack thereof !
Me, I'm waiting to see what it is that's happening on the 19th, and then in July. Until then, I'm not gonna give up the good fight.
To those who got or are getting new handsets of other types...congrats. Enjoy them in good health !
