While Apple might seem busy releasing a brand new operating system and compatibility updates for their apps on the Mac App Store, that doesn't mean apps on iOS haven't been ignored. Pages, Numbers, Keynote, and iTunes U are all receiving small updates that improve compatibility with iCloud, and in iTunes U's case, adds a way to share your favorite courses with friends through Twitter, Mail, and Messages.
Pages 1.6.1, Numbers 1.6.1, and Keynote 1.6.1
Pages, Numbers, and Keynote have received simple updates that improve compatibility with iCloud for instant document syncing. Document syncing requires Pages 4.2, Numbers 2.2, and Keynote 5.2 respectively on OS X Mountain Lion.
iTunes U 1.2
Sharing courses isn't the only new feature — iTunes U 1.2 also adds the ability to search within posts, assignments, notes, and materials from the improved search feature from any subscribed course.
