Um... yes they do. That's funny. Every server between you and the data you're fetching on the Internet knows what you're doing. Your ISP, in this case US Cellular, is no exception. Whether they log it or whether they audit the logs is another matter entirely. They know. It's just whether they wish to take action or not.
It may be vague, but I believe US Cellular is clear enough. Your 5GB 3G plan is for the device you got from US Cellular. If you want to share it, you need to pay for the tethering plan. I do not agree with that, and I believe the tethering plan should raise your cap (by a lot) because you're already paying a lot. And as they say, tethering will boost your data usage. But that is just what I think. What they say goes, and we sign a contract agreeing to abide by their rules.
Being able to tether is just a function of the hardware and software. The WiFi modem goes both ways, and you can use it to turn your phone into a router. And Android supports this. Doesn't mean you have permission to use it. It's like filesharing. You can... but if you do, you may be penalized.
And they may ignore tethering usage if it's small... or they may not. The point is, the rules are clear and they have the means to tell whether you are or not.
