I just had an online chat with a vzw rep and they said that it wouldn't affect the unlimited to swith from a 3g to 4g phone. I then copied and pasted your response, and got
At least he admitted he doesn't know for sure about any of it.
+1 for the online rep admitting he wasn't sure. The store rep showed me what he was talking about when I was there. I just called and asked to double check and the phone rep said she wasn't sure but asked her supervisor and said it "should" be fine but was not 100% either. They for sure can say it would be fine from 3G <> 3G & 4G <> 4G.
