"We’ve got all the details on how to manually update your Droid to the official, Verizon-and-Google-blessed build of Android 2.1.

All in all, it should take you about 10 minutes. There is no “hacking” required – your device doesn’t need to be rooted, overclocked, underpantsed, or what have you. This is the same package you’d be downloading from Verizon (it even comes from Google’s server!), just a whole lot sooner."

Here’s how to do it:

• "Download the update package from here. Don’t unzip it! If your browser automatically unzips things (like Safari on Mac, for example), use a different browser. It MUST stay zipped....
• 
  
• ...Bam! Download, rename, reboot, hold a button, done. Could it get much simpler? As soon as the upgrade process finishes, you’ll be Android 2.1′d up and ready to go."
