The on again off again saga that is the Droid 2.1 update is on again, hopefully. Engadget has gotten their hands on an internal memo that that outlines the OTA update for the Droid. At noon today, which has come and gone, 1000 Droid users should receive the update and by midnight there should be 9000 more. And by Thursday, almost all Droid’s should receive the OTA. Judging by how this was handled so far, I wouldn’t get my hopes up too high. The full memo is after the break.
