Microsoft released OneNote Mobile for the iPhone, iPod touch, and iPad for free download from the iTunes store. The product will be free for a limited time period, the end date of which Microsoft isn't specifying today.
Microsoft OneNote Mobile is the easy-to-use, powerful note-taking application for all of your ideas, brought to you by Microsoft Office. OneNote Mobile lets you create and view notes and lists whenever you need them. Sync your notes with free Windows Live online storage and access them from virtually anywhere using your phone, PC, or almost any web browser.
OneNote Mobile for iPhone lets users take notes, capture and embed photos from their iPhone cameras and sync these automatically to their SkyDrive accounts, allowing them to access/share the notes across their Windows PCs, Windows Phone 7 devices and iPhones.
Supported browsers for OneNote on iPhone include Safari, Internet Explorer, Firefox and Chrome. There is no "out-of-the-box" Live Mesh or DropBox support for OneNote for the iPhone.
