I did the manual 2.1 update and everything went smoothly, except that Google Earth does not show up in the Market. The Earth Live Wallpaper does, but not Google Earth. I tried following the link from the home website, but all it did was force close Market. Isn't Earth supposed to be available after upgrading to 2.1? If no one has an answer, then can you tell me if its possible to undo the manual update?
