Verizon can't stop me from doing it per the terms of their block c licenses.
I'm a recovered Verizon customer, and trust me when I say this: Verizon will never do what they say, nor what they signed up for, nor what most of us wish for them to do, and definitely not the smart things T-mobile and to a lesser extent AT&T are doing about device contracts, etc.
While your statement is correct, it's not because your device still has a stupid damned CDMA radio in it. Until that goes away, Verizon feels they don't have to abide by the more open parts of the Block C licenses they got for LTE. They've even told the FCC as much and the FCC hasn't to date done anything about it. One of the reasons Big Red didn't sell the Nexus 7 LTE is because it'd be the first CDMA-free device on its network, in my opinion, and they really DO NOT want that.
Verizon will continue to be the gestapo that they've always been. My eyes were opened by their ham-handed dealings and outright lies about the Galaxy Nexus. I broke a 2-year agreement a year in to get out of their controlling realm.
Haven't missed a thing with T-mobile. And my bill is literally half and I get more of everything and official unlimited data. If you have decent T-mobile signal at work/home/whatever do it. You won't miss them. At all.
