Microsoft has officially renamed SkyDrive to OneDrive. Microsoft announced the rebranding of the storage service last month after a trademark dispute with British pay TV service BSkyB.
Microsoft also launched a new referral program. If you get a friend to sign up using your link, you will get 500MB of free additional storage up to a maximum of 10 friends (5GB).
If you enable automatic photo upload through Windows, iOS, or Android, you can also get up to 3GB of free storage.
