Yeah, I am having trouble getting mine to work.

I deleted the extension:

HKEY_LOCAL_MACHINE\Comm\InternetSharing]
Extension="" Delete the "isext.dll" entry

I only had a minute to try it though. It was asking me for username. Maybe I didn't select Sprint Data, I don't remember. It also had errors saying it couldn't connect. I'll keep trying though. I probably just missed selecting something.
