Cellular providers should not be allowed to charge "PREMIUM RATES" for services such as data tethering.
They need to realize that they are just "dumb pipes" for delivering 1's and 0's. They are a utility, and should not be charging additional rates for data usage. The radio in my phone can move data at a set rate based on the service it is receiving, but once that data gets to my phone, it's none of AT&T's darn business what I do with it. If I want to download a 100MB picture and then delete it, that's my prerogative. It's like the water company charging you more for water you drink vs. water you flush down the toilet.
It's an intolerable and unacceptable, policy, and denotes monopolistic collusion among the Big 2 providers.
