With the My Phone service, information on your Windows phone is backed-up to a password-protected web site hosted by Microsoft. If you lose your phone or upgrade to a new phone, you can restore your information easily.
Microsoft My Phone makes it easy to share photos taken with your phone. From your My Phone web account or directly from your Windows phone, you can share photos to Facebook, Flickr, MySpace, and Windows Live.
From the web you can organize contacts and appointments on your phone, and search through your old text messages. Changes appear on your phone the next time you sync.
The My Phone service can show you the last known location of your phone on a map (based on where it last synced or shared photos using My Phone).
