I use to be like that. Now that I've gotten older, i don't do stupid things anymore. 

Just try to resolve it, if it happens you don't get your unlimited data back, just sign up for a 3GB plan and you should be fine.

Verizon doesn't even grandfather unlimited data anymore. When iphone first came out they promoted unlimited and many jumped ship, but now they are paying more for the same service with less GB data and no unlimited grandfather.
