Once Alexey suggested me to use online service Mobical to store info from my mobile phone. I didn’t start use it immediately. But recently I decided to try it. It’s really cool and useful service. Once registered there you can synchronize phone book, calendar, tasks and other stuff from your mobile phone with your online account. Moreover, it’s possible to export your contacts as vCard-file and calendar as vCard-file or iCalendar-file for backup or for some other reason.
