Are they still grandfathering in unlimited data plans?
They should, it's what they're supposed to do.
If you read that note about the Nexus I believe that was towards new customers or people considering getting a smartphone.
You already are grandfathered into unlimited data if you currently have a smartphone, the day Verizon stops people from keeping unlimited data and upgrading, you will know. People will not be too happy, but for now your fine.
