Android Central received an anonymous tip providing details into the timeline for the 2.1 update which will start to roll out to Droid devices tomorrow.  It looks like we’ll see just a few updates tomorrow morning, a 24 hour waiting period, and then a big blast on Saturday assuming there were no issues from the initial batch…

* The first batch of 1,000 updates will be pushed out at 9 a.m. PDT.
* Assuming all goes well, another 9,000 updates will go out at 8:59 p.m. PDT.
* After that, there’s a 24-hour waiting period (to make sure all’s still well.)
* Then 200,000 updates will go out on Saturday, March 20.
* Another batch of 200,000 goes out after that, until everyone has the update.

For those not wanting to wait until Saturday, we can only assume that one of the first few thousand to receive the update will leak an update.zip.  And once that file drops, we’ll be sure to have it for you.

Update 1:03PM 3/17: Matt, the forums manager at the official Motorola site, has fulfilled his promise of notifying everyone that signed up at this post when the update would start to roll out…

The Android 2.1 upgrade for DROID by Motorola is being deployed to a small number of Verizon Wireless test users tomorrow afternoon.  It is expected that the broader phased rollout to all DROID users will begin shortly thereafter—we will keep you posted.  A list of enhancements included in the upgrade is available here.

Finally, the guy says something worthwhile.

Update 2:38PM 3/17:  Android and Me just received word from an anonymous tipster as to the original delay from the OTA update we were expecting back in February…

“Not sure if you’ve heard, but the real reason for the latest delay on the Android 2.1 update for Droid phones is due to Motorola’s distribution vendor (Bitfone- now owned by HP). They are having capacity problems with a) the Bitfone application that distributes the updates and b) capacity issues with the current network infrastructure that hosts this application. I spoke to one of the engineers personally and they mentioned that Motorola reps have been “bugging them all day” because of the 3/18 commitment date.”

I guess we should still be crossing our fingers.
