I did the [HKEY_LOCAL_MACHINE\Comm\InternetSharing\Settings]
Delete The Following Key: "ForceCellConnection"
AND
[HKEY_LOCAL_MACHINE\Comm\InternetSharing]
Delete the .dll thing.
Tell me if it works dude
PS
Sorry that is supposed to bring the drop box back to phone as modem or Sprint. Choose Sprint on internet sharing app, connect after the "check connection" thing shows up, and you should be theoretically fine. If not, you can always try the bluetooth setting, I had to choose that for my Mogul...
