Actually I am typing this on my netbook tethered to my rooted D2 running the leaked Gingerbread. I flashed the TBH patch and sometimes can wifi tether with the 3G hotspot that comes with Gingerbread but when that flakes out I have so far always been able to at least usb tether over pdanet (from the market). The TBH patch should make the data appear to be going to my internal phone browser rather than to a tethered device so I should not appear to be tethering to big brother. However I haven't seen a bill since I started doing this so I can't say that for sure. I do know I tethered quite a bit under the stock froyo and never had an issue even though I do not use the VZW tethering plan, just the unlimited phone data plan. Cuz
FYI, p3droid said to remove hotspot hacks and not to use any free tethering software for the time being. Apparently several carriers are now able to track who is using the tethering.
When I said it doesn't work anymore, I meant it would be in your best interest not to use it. IMO, that's the reason for all the lock down on moto's phone.
