You can manually edit the phonebook database with SQLite Expert Personal 2 edition on your PC. Make a copy of the database file which is stored on My Flash Drive\user\userdata\phonedata and paste it to an SD card. Open the file with the SQL lite application on your PC. You can add contacts manually. It may be possible to export the contacts from your phone to an CSV file and then import them into the db but I have not tried that. I had 600 contacts in my iPhone 3GS. I did not need all of them so I removed what I did not need and manually added the rest. Copy the edited file back to the F500BT
