Absolutely not rooted. Why? I never connect myself to WiFi networks, as LTE is in 90% faster than most of residential WiFi connections. SO everything is being done on LTE, video streaming, WiFi tether, USB tether, SpeedTesting, uploading videos, photos, now Skyping. It's basically battery powered DOCSIS 3 Wideband modem in your pocket.
And it's unlimited! Why depriving yourself of your own 50mbit speeds that are there for you to use them. I never understood that perception. I work 5 days a week and it's not lik I'm trying to purposely use it. The sheer speed of LTE network is the main factor for high usage and you can't simply compare this with your 1mbps EVDO usage.
Verizon is basically testing to see what the average usage will be on LTE phones. USE IT!!!!!!
