Froyo 2.2 update fix

I updated from (Droid 1) 2.1 to 2.2 the other day just before they pulled the update because of some issues. I am wondering how I can go back to 2.1 until the 2.2 issues are resolved. I am currently experiencing problems....volume control only allows you to go as low as vibrate, not off. Screen goes from portrait to landscape but sometimes goes to the opposite landscape, meaning screen is upside down if you open the keyboard.
