Verizon has awesome coverage, but their data plans for anyone not grandfathered are shit, even compared to AT&T who still lets you get a normal individual line and 3GB for $30.Everywhere I go, I have Verizon 4G LTE and I average 40mbps in the Seattle area. YMMV.
I hope T-Mobile steps up their nationwide coverage, and if those Sprint roadmaps are true, I'm excited. I can't wait for CDMA to become extinct.
