Apple just seeded the 3rd beta of iOS 6 to developers. I am sure they are wrapping things up and almost ready for an official release. iOS 6 beta 3 has a build of 10A5355d. There are no huge changes but here are a list of some of them:
-There is a new Maps section in Settings for controlling unit labels (miles or kilometers), label sizes, and label language. Users are also able to now control the volume of turn-by-turn navigation.
-Safari now has glyphs for bookmarks, reading list, and history instead of worded labels.
-Reading list sync icon in the Safari menu bar on iPad.
-Apple has been busy updating the maps application.
-users can now have iCloud email addresses at @icloud.com, not only @me.com.
-Also released is Xcode 4.5 Developer Preview 3
