Microsoft My Phone is a free service that helps you backup/restore and manage data on your Windows Mobile smartphone. The My Phone app on the smartphone "talks to" a password protected website (you need a Windows Live ID for this). Contacts, calendar, tasks, photos/video, music and documents stored on the smartphone is synchronized to the cloud. You need to change the default configuration to deal with data stored on a flash card.

Access to this service has been limited until this past week. However, you can now go to the service's site...
