I know a person who went in to upgrade to the Droid Razr Maxx on July 2 from the HTC Thunderbolt. He was ready to pay the full price to keep his unlimited data, but Verizon wouldn't honor it. He escalated it to the manager of the store and was still refused. He was told by the manager that this may have been an option at one time, but it's not something that is set in stone and is subject to change at any time. He left and is still weighing his options.
