Out of nowhere, Blue Wireless is participating in this. Blue's network has been pretty bad up until this point only offering 1x service. What I don't understand is that Blue's coverage is only cities. Cities that Sprint covers nonetheless.
In New York:
All have native Sprint coverage and some have 4G LTE. I'm in Scranton and we definitely have Network Vision rolled out here. Blue's plans beat everyone else though. $46 for everything including unlimited high-speed data. Blue definitely runs its own network too.
