I emailed VZW asking about the grandfathering and recieved my response this morning. It looks like as long as you have unlimited BEFORE 7/7 you will be good no matter what. It is only if you add a new line or upgrading from a feature phone to smartphone. Here is my email verbatum minus my last name for protection. So regardless it looks like you get to retain it as long as you keep your plan.

Dear James xxxx,
Good morning Mr. xxxx. I can understand your concern. My name is Dana and I am eager to clear up any confusion. I am delighted to inform you that your existing unlimited data plans for each of your lines of service will not be changed and you can retain it, even if you upgrade from your Blackberry Storm 2 to a new Smartphone, such a the Motorola Droid Bionic . The new data plan pricing, which has not been officially released and cannot be commented on until an official announcement has been made from Verizon Wireless,
applies to new lines of service only and existing lines upgrading from feature phones/multimedia devices to Smartphones. I know waiting on a device can seem like forever. I wish I had a date to provide however we do not like to raise expectations that may not be met. You may also receive free e-mail updates as to when new products and services are available.
