I think its ridiculous to charge extra to use the same amount of data, in my case at least since I have a 2GB plan. Who gives a shit how you use it, you have 2GB and thats it. You are already charging $35 fucking dollars for a measly 2GB so just let me tether. Now you unlimited guys, they kinda have a point for you not tethering since you could be downloading all the pronz on the web and killing there service, but I think if used responsibly you should be allowed to as well.
