Basically, by calling sprint and telling then what you were doing, you were basically telling them that you are trying to tether without paying them for it. Of course they won't help and tell you anything. Your straight out telling you trying to go around them and not pay for it. I'd expect that there's a good chance that they are monitoring your account data usage now.

Last time I looked you don't need a username or password. I haven't tried this program my self yet, but others are reporting that the TP2 doesn't work with this and can cause problems. That's why I haven't installed it yet.

If you really want to try it though, I'd suggest getting a good backup program and using it before any mod like this. That way you can back out of it if you need to. Saved my bacon more than once.
