So I'm thinking about upgrading for this bad boy (although I might hold out for news about the "prime"). Anyway, i have an OG droid w/ unlimited data right now and I know my plan is grandfathered in, but the one thing I've never been clear on is whether or not 4G LTE is considered a separate plan. Do the unlimited Data plans differentiate between 3g and 4g? If I got the Bionic would I have unlimited 4G automatically per my grandfathered unlimited plan? Thanks in advance for any replies.
