The official build of the Android 2.2 update for the Motorola DROID has been leaked and posted on MyDroidWorld. Please not that this update is for the Verizon branded Moto-droid for USA and NOT the GSM Motolra Milestone . We wont recommend you to get this update unless you have a spare DROID and are desperate to get FroYo on board !
Several users are reporting that the update is working but still it’s not ready for end-users and we don’t advise you to try unless you know your way around.
This is the FRF84B build of FroYo and is expected to be rolled out via OTA soon to Verizon users.
