Re: "unlimited" data not unlimited data Sprint is unlimited, but good luck finding the point where they throttle. I've had the service about 14 years and their network is slowest in the nation. There are a few markets with 4GB (right outside Crystal City, VA) and I saw 15-20mbit.
However, I was only visiting. Most of their network is 3g and you're lucky to see 100 kilobits each direction. 12KB/S up and down...So not like you're going to be able to find their invisible cap all to quickly.
