Everybody should be clear on one thing....while i have been tethering causally for years without any additional plan addons, and i have never seen any charges for it, there is no guarantee that Sprint can't see what you're doing, and they might decide to crack down and charge, particularly for power users.

Regardless of how you connect, there is a way that Sprint can tell, the question remains, will they do anything about it. As always, Caveat Emptor, or in this case, usesr beware.
