What a great day for Motorola Droid owners - your Froyo update that you've been patiently waiting for is finally here. You can upgrade your ESE81 (that's your old Éclair) to what is now called FRG01B (this is your Froyo) using the link below.
It is unclear yet whether the upgrade is showing up when you ask the phone to update in Settings > About > System updates but we have preliminary reports that it is not. However, you can upgrade manually using the procedure below.
This post will be updated throughout the day.
Warning #1: Applying this update will unroot you if you are currently rooted, pending further notice.

As part of the Android's open source Apache license, manufacturers are required to publicly release all of their own modifications and improvements made to the Android core. Today, both Samsung and Motorola decided it would be the perfect time to drop the Captivate and Droid X code to their respective open source sites.
This will allow ROM developers to figure out all those little quirks specific to the hardware and incorporate them into their releases.
Note, however, that the Android license doesn't cover proprietary extensions, such as custom vendor applications and widgets, and therefore does not require manufacturers to open source them:
With the exception of brief update periods, Android has been available as open source since 21 October 2008.
