If you got the Kindle 2.5 firmware update, consider yourself lucky. Amazon has announced that it’s pushing back the update for everyone else. They need to make some “small adjustments” based on user feedback.
We have no idea what those adjustments are and Amazon isn’t offering a new date for the update. So we will know whenever they see fit to tell us. All we know is that they will be rolling out to “more users over the coming weeks.”
