Microsoft Phone Data Manager Beta application will help you to sync your data to your local computer, so you don’t have worry about losing this data. It synchronizes your phone contacts with Microsoft’s Windows Live Contacts store in the cloud.
Contacts: Microsoft Phone Data Manager Beta syncs your phone contacts with your contact store on Windows Live Contacts, the same store where your hotmail contacts are stored. Your contacts data is always a click away via Web, if you lose any of these contacts or change your phone simply re sync the contact list to your phone. You can edit your contacts any time, these changes will immediately reflect on both your phone and Windows Live Contacts Store.
Music, Photos and Video: Currently the application can only download these media files to your local computer only, it can’t sync to the cloud yet.
You can do the downloading via bluetooth or using a USB cable. To use the syncing you need to have Windows Live ID. Works with Windows XP and Vista 32 bit systems.
