"The FCC concedes that Verizon may charge $20 per month for customers who retain grandfathered unlimited data plans." http://arstechnica.com/gadgets/2012/07/tethering-apps-must-b...
So I won't be benefitting from this. The most ridiculous, bullshit part of all of this is that unlimited plans aren't unlimited anyway. They have "Fair Access Policy" data caps (5GB for Verizon IIRC) that are just like the modern plans with a tad higher caps. They just advertise differently. It's the same damn thing. And I don't get free tethering. Ridiculous.
