Up until today, Verizon's website used the term 'unlimited' to describe their EV-DO service. Apparently their definition of 'unlimited' didn't mesh too well with reality, because not only could you not go beyond 5GB/month, things like YouTube & P2P apps were banned as well. Unlimited indeed...

"Verizon has been dropping customers for the past few years for excessive data usage, but the actual limits weren't until recently revealed in the terms of service (TOS)."
