Now you can sync contacts, calender, task, notes and bookmarks with the Sony Ericsson website in a "cloud service". First you have to register an account at Sony Ericsson then you have the settings sent to your phone or manually input them. Then you can sync what you want and your information will be stored on the SE website. This provides a great back up tool for your info. I just used it yesterday to sync my K850i contacts and it worked perfectly.
