Investment to improve core network?!? WTF are you talking about? Last I checked, Sprint is actually faster than the two litigation-happy babies, AT&T and Verizon. And although they still do CDMA, they also do Rev. A EVDO, and they rolled it out way before them.
Sprint may have hit-or-miss coverage outside I-95 corridor, but where it does work, it works phenomenal.
