If your Evo 4G’s been rooted already (using either the Unrevoked or XDA method), there’s now another Wifi tethering method available at your disposal, and all you have to do is load up a little application (just be sure to grab the latest version). This one is outside the confines of Sprint’s official $29-a-month option on the Evo, so you’re own if somebody shows up at your house asking about your kneecaps.
