I had to post that even I, a total nube, managed to do the manual download / update. I was a bit nervous, as I have never done anything like that to my phone. It was on the "red eye" screen for what seemed like forever, and I was worried, but it ultimately rebooted and I'm definitely running 2.2 now. I also downloaded the Flash player. Following up on earlier posts above -- going to the 'notifications' screen didn't work for me; so I went to the download itself (in the download director) and clicked on it, and was prompted to "install" the application, which I selected, and it installed fine. I also grabbed the "Adobe flash showcase" from the marketplace, and it installed and runs fine.
NOTE: I had to use the Google link to install; clicking the link for "update.zip" does not work, as Megadownload took it down as allegedly violating the terms of use. Make sure you download into your sdcard root directory (not a subdirectory) and be sure to rename the file "update.zip," as the directions tell you to. Also, when you download the Flash player, you will have to use Megadownload and unless you want to pay for premium service, you'll have to wait 35 seconds. Be patient and wait for the free download button to appear.
Only issue so far -- I had a live wallpaper running (3d party), and until I disabled it, the phone was jerky and slow (I even had the latest update on that installed, which purported to be updated for Froyo). I won't besmirch the developer by naming the app, b/c I'm hoping he'll fix it as it was my favorite all-time wallpaper.
So, that's it for me for now. My main reasons for posting are to: (1) encourage even total nubes to try this; and (2) tell my fellow nubes not to worry if the "red eye" seems to be on forever.
Good luck, all of you as impatient as I was!
