The move, Microsoft said in a blog post, comes as people increasingly need access to files on-the-go.
"As devices proliferate, having a great experience on the Web is only one piece of a pretty complex puzzle," Microsoft's Mike Torres wrote. "People are choosing where to put their files based on how portable and accessible they are across the various devices they use; therefore, it's critical that we continue to extend the SkyDrive experience to the devices you use every day."
To that end, the most recent version of Windows Phone, known as Mango, included deep integration with SkyDrive via the Pictures and Office hubs, allowing for the sharing of photos via text, email, or IM, for example.
But users wanted more, Torres said. "Many still want the full SkyDrive experience from Windows Phone, including tasks like browsing their entire SkyDrive, sharing links to folders or files, deleting files, and creating folders." As a result, phones running Windows Phone 7.5 can now download the SkyDrive app from the Windows Phone Marketplace and do just that.
For those on iOS, the same app was also released in the App Store. See the video above for more.
