if you go into contacts, select menu>>more>>import/export>> export to SD, and click confirm or yes this will put all of your contacts on the SD card in vcf format, all you do is then get that onto your desktop (email/bluetooth/usb cable), load up Gmail, click on contacts, and then on more options, click on import, and find the vcf file you just created, this should be spot on. but test before you delete phone contacts!
