Well when one of our asst. mods insists on adding fuel to this fire, you may as well expect it. Verizon is on board as many have stated from their test text of keywords and the proof you have provided.
Actually, isn't the "Supported Carriers" a list of companies in the USA that GoIP's technology is compatible with? I believe so. That isn't necessarily a declaration of companies contracted for service.
We would all like positive affirmation of Verizon being on board, but this is not it. It will come. We just have to wait.
