Microsoft has launched a website promoting its new 'My Phone' backup and sync service.  According to the information now posted to the site, users of My Phone will be able to back up contacts, calendar appointments, text messages, photos and other information online; share those photos with others; update the information from a computer using a Web-based interface; and use the stored data to restore a phone transfer it to a new device. Microsoft said it would give each user 200MB of storage space, but warned that only phones powered by Windows Mobile 6 or later would be compatible with the service. In fact, it hedged: "Most phones that run the Windows Mobile 6 operating system are compatible with My Phone service," said the service's site. Although not strictly billed as a phone-to-PC sync service, My Phone will synchronize Windows Live contacts -- assuming Windows Live has been installed on the phone -- with those on the Windows Live Web site. However, My Phone will not sync contacts, e-mail messages or to-do tasks with an Exchange mail server. Phone data will be backed up to the remote servers automatically once per day, said Microsoft, although users can manually trigger a backup at any time.
