I'm very confused to why ATT(and other phone companies) are able to charge extra for the ability of a phone to tether. Tethering is a hardware feature, and has nothing at all to do with the phone service. Its the same as the phone's ability to use bluetooth or sync with a computer.I don't see why it has anything to do with the phone service and wonder how they got into that space to begin with? The only justification I can see is that when one tethers, they might end up using more bandwidth. However, that does not justify the extra price for tethering, since whether you tether or not, you still are restricted to the same bandwidth cap as non-tethering customers. So looking at the new ATT plans, if you don't tether, you are allowed to use 2 GB a month for $25. If you do tether, you are allowed to use 2 GB a month for $45! ATT's network is not affected at all by tethering, so the only justification for charging $20 extra is gouging the customers.
