More details on the new iOS OneNote client (see the main link below for installation instructions and additional info)
Since I began looking at Microsoft Office 2010 Beta feedback last year, the one question so many of you asked perhaps more than any other was "When will you release a OneNote app for the iPhone?" I'm happy to say that the time has come. First, check out the official announcement by Takeshi Numoto, corporate vice president of the Microsoft Office Product Management Group. Then head over to the iTunes App Store to download OneNote Mobile for iPhone. It works on any iPhone or iPod touch running iOS 4.2 or later, and it's free for a limited time.
With OneNote Mobile, you can create and view notes and lists right on your iPhone. Your notes can be synced with your Windows Live SkyDrive account so you can access, edit, and share them from virtually anywhere. (Don't have a SkyDrive account yet? Sign up here — it's free!) You can also use OneNote Mobile for iPhone to view and edit any of the notes that you've created on your computer and synced to your SkyDrive account.
