What's so special about gutting the network? They HAD to gut the network because they left it to crumble, whereas the competition spent the last few years upgrading backhaul and adding capacity.

VZW: $80 billion+ since 2000 (

Even if Sprint is spending more (of which you have no proof), the big two still have better reliability, coverage, and data speeds. And this is just the beginning. PCS/AWS LTE should be up soon to improve their already class-leading speeds.
I somehow doubt a small-fish, like Sprint, is investing more into their mediocre network.
EDIT: total NV investment is $4-5 billion dollars. (

So you are lying and spreading lies. AT&T is spending almost 3x more money on their already solid nationwide network.
We've been hearing this for years. They
still have nothing to show for it. Even TMobile has leapfrogged Sprint's LTE deployment.
