Unfortunately, the Droid X does not have Froyo yet, nor is the bootloader decrypted yet, so there's no way to get 2.2 on it as of right now. Hopefully it gets it soon, since the Droid 2 announced today does have it.

I also wouldn't be surprised if tethering were disabled in 2.2 for the Droid X like it is on the original Droid.
