you can use another lines upgrade on your plan and keep unlimited data...however nobody on your plan including yourself can use the upgrade on your line without losing unlimited. this is nothing new alot of us have been doing this for a bit now. Enjoy the note2 its a great device!
that would work IF someone in my family plan didn't want to use the upgrade
thats the only road to take if you dont want to lose your unlimited data on your phones.
BTW you cant really tell any Verizon guys to do what was done for me ... they'll laugh at you all day lol.
