The link above is to the ACTUAL update downloaded when your phone tells you its time for the update to be applied.
It is DIRECTLY from Google.
You download that, rename it to update.zip and place it on the root of your SD card. Then go into recovery mode (X+Power, Camera + Volume Up) and apply update.zip from the recovery menu.
Takes 3-4 minutes to boot and BAM 2.0.1 instantly.
OK... now you've got my attention!.......
You have to hit all 4 of those functions at once?
No, you need to first copy the file to your sd card, then turn off your phone
while turning on, hold X. You'll get to a screen where there is a hazard sign and exclamation point. From there you need to hold volume up and camera until you get to a screen that has your options.
