A clear explanation from a VZW connect that outlines how the OTA updates work for the Motorola DROID. At noon today, approximately 1,000 people received the notification to update their handset. At around midnight this evening, 9,000 more will receive it. After the initial 10,000, there is a 48-hour waiting period. No one after that receives anything until December 10th at 12AM, which will be 200,000 people. It will continue at 200,000 devices a day until everyone is updated.
