[UPDATE]: For those that are worried about the manual update voiding your warranty, you may just want to hold off until your phone gets the OTA version. Or that’s what VZW support tweeted, anyway. Still, I can assure you this is the official release and the exact thing you get on your phone with the OTA, and it is coming from a LEGITIMATE Google server.
And so it was written: the gods (see: Verizon) saw it fit to bestow upon the lowly of the world an update magnificent: from the ashes of old would rise Android 2.1 for the Droid Eris. Alas, that cruel, ugly, villainous Time reared his head once more: many the humble and meek would need wait weeks more to receive the gift which had already descended from the cloud for others. But nay, no longer shall ye wait!
That is because the official update package can now be downloaded from Google’s servers and installed manually onto your Droid Eris, and for the impatient here is how:
Voila! Android 2.1 on your Droid Eris. The whole process should take about 15 minutes. Enjoy.
[Note: as Marc points out in the comments, if you have previously installed a leaked version of the update this one won’t work with your phone. You’ll need to be running your Droid Eris stock.]
[UPDATE]: As there seems to be some confusion I would like to clarify that this is the OFFICIAL release that is being sent out to handsets and therefore you will get the exact same update as those who have received the OTA. This is not a leak or a pre-release build, and is totally legit for installation. The one catch is the manual update will wipe the phone, so be sure to back up your important info.
