backup phone contact

We already have a great solution from google product for backing up mobile phone contact and calendar. With calendar on mobile phone, just only important for someone like me, so busy and always go around, can't remember the things to do, a lot of friends and many repeat important anniversary in year.

In Symbian phone, or linux address book, you can easy backup your contact list and calendar to file. Contact list will be backup in Vcard format with .vcf file, calendar is .csv file. So easy to import them to gmail contact and google canlendar. This way make 2 advantage rather than normal way backup, your storage media may be good and safe but google is beter, and you can view / edit you contact and canlendar on google !!! z that great ?

I have never use pocket pc or iphone, so i don't know what exactly format file of contact list and calendar in these OSs. So try to ? Vấn đề là mình hồi nào giờ xài Sony p990 với p1i, cuối tháng mua HTC Hero, nên chắc cũng chưa được xài qua WM và Iphone OS, nhưng sure là có app sync calendar và contact lên google, nó có app download về cài vào, thấy đâu đó rồi.

Nice day man
