Spoke with VZW about the tier data and grandfathering. All data plans are grandfathered. If you have unlimited data now, and you do not get a new phone and plan before it is implemented, you should still be grandfathered in. I asked specifically if in 2 yrs my plan comes up again and I renew, will I keep the unlimited data even if no longer offered and his replay. Yes! the system does not look at plans of those who have them. He said that all it asks is IF there is a data plan, if you do not have a data plan and they put tier'd data in place then you are hosed forever. So if you have your plan now, 3 or 4G, you are good.
