Microsoft on Tuesday updated its OneNote Mobile app for iPhone (free, App Store). While the original app was exclusive to the US, OneNote 1.2 for the iPhone is available in Australia, Canada, Ireland, New Zealand, and the UK. The update includes an improved search function, the ability to pin notes to the Recently Viewed list, and a sync function for shared notebooks on the web with Windows Live SkyDrive. Notes synced to SkyDrive requires a free Windows Live ID and can be accessed from any supported web browser with the free OneNote Web App.
