Using its Skydrive Cloud servers, Microsoft is now allowing iPhone users to access, edit, and share their desktop OneNote application data on iPhone.  Microsoft has long been talking about bringing their Office applications and functionality to the iPhone and this is the first indication of doing that (OneNote is part of the Office suite).

While the OneNote Mobile app naturally doesn’t have all of the functionality of the full OneNote 2010 desktop application for your computer, it’s optimized for your iPhone’s display and lets you handle the basics with ease. Use OneNote Mobile to create shopping lists and to-do lists, prepare for a trip or project, and take class or meeting notes without lugging around your laptop. OneNote Mobile is also great for collecting ideas and tracking project notes, capturing ad hoc information about stuff you need to deal with at home or at work, as well as tracking activities, wish lists, gift lists — anything you can think of.

The app can be found here, more screenshots below.
