Now my question is as you can see the 4G and 3G pricing are the same its 29.99 unlimited now if we are on a 29.99 unlimited 3G plan now and they switch to a tier plans now if a went out and got a new 4G phone would i still be grandfathered in where i have a 3G data package now or is the 4G a whole different plan setup. where the new phones are run the 4G would someone have to switch there data plan or could you just replace the phone on the account and be good to go?
