Unless you had an unlimited plan from a few years ago (or older), you aren't getting on a new one. Others are right though - if you can buy someone's out and merge, you are good to go, otherwise you have to look elsewhere on other carriers/vendors. I'm on a corporate plan I've had for years with unlimited, but I have to watch any phone upgrades or changes like a hawk, as they'll remove the plan almost every time. Takes a call to the 800# to fix it too, 'cause the reps in the store can't see it (unless looking at my plan with it on there) or change it back. They can break it, but they can't fix it - go figure.
