Now that I have the Froyo update I've tried both USB and wifi hotspot tethering (3G only, I can't get 4G at my house) and they both give the same "Error 67: Registration Failure." message and then quit. Looks like Sprint has shut down all tethering in Froyo unless you pay the extra fee.
I've also noticed that the portable hotspot option (seen here) is missing from the Tethering option in the Wireless and Networks settings and any shortcuts/widgets that toggle the hotspot run the Sprint Hotspot app.
I know that some people were expecting limited tethering without the extra contract since it's a feature of Froyo but looks like we're out of luck, at least on the stock Rom.
