Microsoft My Phone syncs information between your mobile phone and the web...

Apparently, they've re-branded SkyBox and are bringing lots of cloud syncing fun to WinMo phones.

Microsoft My Phone syncs information on your mobile phone to a storage space on a web site hosted by Microsoft. If your phone is lost or stolen, or if you upgrade to a new phone, you can easily restore the contacts, calendar appointments, photos, and other information that you stored on My Phone to a compatible new or replacement phone.

What information can I back up on Microsoft My Phone? The first time that you run the My Phone application on your mobile phone, you will be asked to accept or change the recommended settings. Recommended settings will synchronize contacts, calendar appointments, tasks, photos, videos, text messages, music, and documents between your phone and your My Phone web account. However:

* If you have an active connection with Microsoft Exchange server (which is frequently used for corporate e-mail), My Phone will not synchronize your contacts, calendar appointments, or tasks.

* If you have Windows Live installed on your phone, it will synchronize your Windows Live contacts with the Windows Live web site, and My Phone will synchronize your other contacts to your account on the My Phone web site.
