After poking around here for a while and not finding a lot, as well as some digging in news articles, does anyone know what Sprint's Network Vision is ACTUALLY doing? What are the concrete benefits of it? I post here because of the discrepancy in Vision PRLs and regular Sprint PRLs (the most recent versions both ending in 90, I think). There's a small bit on VM's site about it improving our 3G speeds, but does it actually affect us, or is it just freeing up the towers by Sprint users having it?
