Microsoft has ported Office OneNote to Apple’s iPhone and is offering free downloads of the application as it launched on iTunes. Users that want to grab OneNote Mobile for the iPhone free of charge need to head over to iTunes and do so as fast as possible, since the offer is only available for a limited time, a Microsoft spokesperson told me via email.

I’m one of the millions of OneNote users (the Office component is installed on 78 million PCs in the U.S., according to comScore), and if you ask me, I really couldn’t tell you how I managed my workflow before it came along.

As the official label implies, OneNote allows users to take notes, digital notes that is. I love the way it integrates with Internet Explorer, allowing me to quickly and easily save information that I come across on the web in a centralized location always at my disposal.

“OneNote Mobile for the iPhone lets you capture and review notes and lists on your phone. Notes are automatically backed up and synced with free Windows Live SkyDrive online storage, so that you can access them from virtually anywhere - your PC, phone, and browser.

“Collecting thoughts and ideas on the go is what OneNote was made for,” revealed Takeshi Numoto, Corporate Vice President, Office.

Microsoft did not say how long the promotion for OneNote Mobile for the iPhone is going to last, but at the time of this article, a message on iTunes for the app still reads “Free for a limited time.”

At the same time, the Redmond company did not reveal how much it was going to charge iPhone users for the app once it would no longer be free.

“Today's release is another step in Office evolving to serve our 750 million customers worldwide. Whether it's on a PC or Mac, a mobile phone, or online through the Office Web Apps on multiple browsers, we continue to bring Office to the devices, platforms, and operating systems our customers are using.

“It should be about the ideas and information, not the device, right?” Numoto asked.
