Regardless of the Terms of service violation my opinion is this. I paid for unlimited data. The data doesn't cost "more" or "less" if I tethered versus downloading files to my phone and then copying them to my laptop. When I'm home and at a friends' house that has wifi, I use it. I keep my wifi on all the time and try to stay away from having to use Verizon's network. I try to be conscientious of others on the Verizon network because there's only so much bandwidth. I happily use about 250MB/month and I have unlimited data. So far this year I've used less than 2GB combined. I'm a big power user/tweaker, but 99% of my usage is at home and at a friend's house.
If my internet goes out at my house, I won't feel guilty about tethering for a few days. If I go travel somewhere and drink up 20GB in a month because I'm traveling I won't feel guilty. It's a give an take. I try to stay off of Verizon's network as much as I can. But when I want to use it I will. It doesn't really cost Verizon any more to sell me 2GB versus 200GB.
Expected ICS late Q3 or Q4(2012). I called it back in February 2012!
Now Expecting JB late Q2 2013. I called it back in October 2012!
The FCC has ruled that Verizon can in no way restrict 4G LTE data. as part of a areement they made to get the spectrum. They can charge you a tethering fee, but can't limit 3rd party tethering apps or limit unlimited data which the consumer has a right to use as they choose.
File Complaint | FCC.gov Of course Verizon can fall back on the "to preserve network integrity" bit, but not all the time.
Maybe the FCC doesn't do anything because no one complains.
