I knew I'd lose root. It's not really that important to me, I can wait. It's just that I don't see much advantage to froyo after using it for a day so I asked just to be sure there is no way to go back.
Given a choice ... froyo or or having the hotspot through root, after a day with froyo, I think I would prefer the hotspot. Again I just wanted to know if it's possible. If not, I can wait. I know it will come sooner or later. It's not that big a deal as I can use PDAnet if I have to in the meantime.
