I have an unlimited data plan with AT&T. In order for me to tether/hotspot on my Nokia Lumia 920, I have to pay AT&T $20 / month for the privilege and give up my unlimited plan.

On iPhone, I would get around this by jailbreaking and using MyWi. I hardly even used it so I wasn't like I was "abusing" the network. But I found it handy for the few times I needed it for my laptop while not near WiFi.

Is there anything equivalent to MyWi on WP to get around this?

I'm interested in this one too. 😊
