I don't think you will be grandfathered in if you get a new phone and sign a new 2 year agreement 3G or 4G.
Anyone currently on a data plan will be grandfathered in with an upgrade, according to all the info we've had.
Now that the 7th has come and gone, though, I'd like to hear some people actually confirm this.
I would like confirmation on this as well. Documents published so far clearly state that only New Customers and people trading up to a smartphone, will NOT be grandfathered in. If you are going from 3G-3G or 3G-4G or 4G-3G or 4G-4G you WILL be allowed to keep your unlimited data plan.
Ok you lost me, or are you talking about people with regular jitterbug phones upgrading to 3G/4G??
