OneDrive is now live! For the existing SkyDrive users, just head over to OneDrive.com and log in. All of your files are ready in the new OneDrive experience. Microsoft has also added several new features including automatic camera backup for Android and the ability to share and view videos just as easily as photos. The company has also added new ways for you to earn more storage. Customers who refer friends can now receive up to 5 GB (in 500 MB increments) for each friend who accepts an invitation to OneDrive, and you will receive 3 GB for using the camera backup feature.
