replied, you are correct that the 10Mb os pb we get now is pretty irrelavant. But the 40+ we used to get worked out pretty good. It has only been since the upgraade from 22/5 to 27/7 did the PB amount drop and the upload PB go away completely.
THe plan listed on my original bill listed is as, "w/ powerboost" and they have changed the name of the plan at least 3 times since my contract was signed. In my opinion changing the plan even once from what it was listed as on my bill is a breach of contract. However, at the corporate lawyer level, I am sure they will say it is not because the plan option checked is some like, "other high speed plan" which does not pin any name or speed levels.
