For anyone wondering, here is some clarification for those of us grandfathered in on unlimited data. You can keep your data plan, even when you renew your contract, and you will still only pay $30 a month, but you just lose the ability to get a discount on phones (i.e. no more $599 phone for $199 at time of renewal). You just have to buy your own phone (Amazon, eBay, etc.) or buy from VZW at full retail cost.
Here's my chat log with the VZW rep from today (July 12, 2012):
Please hold for a Verizon Wireless sales representative to assist you with your order. Thank you for your patience.
You are now chatting with 'Kayla'
Kayla: Hello. Thank you for visiting our chat service. May I help you with your order today?
You: I am grandfathered in on unlimited data. How long will that last? Will I be forced to switch to these terrible 'Share Everything' plans?
Kayla: I'd be happy to assist you.
Kayla: You will not be forced to switch to a share everything plan however if you wish to keep your unlimited data you will upgrade at full retail price.
You: I am paying $30 a month. For the SAME usage I have now (4GB) does that mean it will cost ($110 just for data) 40+70?
Kayla: Yes but that includes unlimited talk and text as well.
You: Oh, I don't need that. I use less than my 700 minutes
You: So, if I am paying $30 now for unlimited data, then how much will it cost when I have to renew my plan (to stay on unlimited)?
Kayla: Your plan will stay the same you just have to pay full retail price for a new phone
You: So we can keep unlimited for $30/month as long as I have service with Verizon, even into future renewals as long as I buy my own devices?
Kayla: That's correct.
You: Great, thanks for the information. I will save this conversation if that is OK with you.
Kayla: Yes it certainly is.
You: Thanks, have a good day.
Kayla: Is there anything else I can assist you with?
You: That's all.
Kayla: Thank you for visiting Verizon Wireless; it’s been a pleasure chatting with you. Have a great day!

I may not switch to Sprint after all, it just depends on what kind of deal I can get on the phone I want when the time comes. I am very happy now that I have actual ICS on my Bionic though. Stable and everything works, so I think I'll be OK for a while now.
