Need help. no USB tethering on new Sprint TP2

[RadarRider]

Okay I've had a Mogul and a TP1 tethering just fine. I get this shiny new TP2 two weeks ago and absolutely none of the tethering USB reg hacks/cabs do a thing that I can tell. I have unlocked it (verified in boot-loader screen) and have had zero luck getting the connect to stop being that ugly grey color.

One post said I should see another Internet Sharing icon (I don't) or can't find it. I've not had any luck finding "All Programs". If that's my problem show me where/how. When I added Bing it showed up under start and it's voice commands work fine as does Opera. so I at least have data connection.

Anyone have a clue why I can't get this USB tethering working? Wifi is a no-go for me due to battery.

Thanks for you help.--DD
