Microsoft leaks My Phone cloud service.

"According to Microsoft, My Phone synchronizes information like contacts, calendar appointments, tasks, text messages, photos and video content between the user's mobile phone and a password-protected website, enabling consumers to back up their personal data in the event their phone is lost, stolen or broken, as well as transfer information when they transition to an upgraded device. In addition, My Phone will synchronize Windows Live contacts on the phone with the Windows Live website."
