There are some bad news also for the users who have a phone with 512Mb of RAM, not all the features of this update will be available for you.
Go to Settings => Phone Update and see whether it is available for you (manually).
Kumaresh from Tamilnadu says that the download status is stuck at 0%.
It may be due to the heavy server load. So if any one of you is able to update your phone just leave a comment.
