UPDATE: i did some DATA tests last night, and its sad to say but the sprint radio SUCKS BIG DONKEY BALLS!
i set up a ping test that ping'd open dns servers continuously. after 30 min of pinging mere bytes of data to the dns the device was so hot it could have basically melted AND it drained my battery from 80% to 30%. that's OUTRAGEOUS! the telus radio would never have done this. Its sad to say but you sprint guys are not crazy
the radio does suck the big ol' kawk. so i hope sprint releases a better radio for you guys. and i hope i can find a telus radio for u guys to try and for me to flash back to.
long story short, cliff's notes sprint radio sucks a$$ on EVDO.
