You don't use widgets? Like the news and weather one? Not a problem.

1. Download the update -- the .zip file located above -- and rename it to the default Android OS update package name. Conveniently, this is update.zip. Do not extract the files!
2. Place file on the root of your SD card.
3. Power your phone off.
4. Boot into recovery (Hold Power + X).
5. Wait for a triangle with an exclamation point to appear. Release the power button and X key.
6. Press the volume up and camera button at the same time.
7. Using the d-pad (the square thing next to the keyboard) select “apply update.zip” and press the middle of the d-pad (gold-looking button).
8. Your phone will now attempt to install the update.
9. When it finishes, use the d-pad to select “reboot phone”.
10. Your phone will reboot with Android 2.2 unless something went wrong.
Now, when you rename the file, rename it update and see if you get a warning about changing the file extension. If you do, you'll want to name it update.zip. If it doesn't warn you at all when you name it update, it's already named update.zip and you'll just roll with it like that.
