Geek: "Earlier today we reported that Microsoft may have inadvertently turned on its SkyBox service ahead of schedule. Now we have official word from Microsoft that the My Phone web site is in fact the new service and it went live prior to its scheduled debut.
The My Phone cloud service will sync contacts, calendar, photos, video, and more from a mobile phone up to the cloud, allowing you to back-up and restore from the service. You can also edit and manage all of your information through the Web portal.
Microsoft is planning to release additional information about My Phone and begin a limited invite only beta at Mobile World Congress."
