To manage some contacts on an mobile device I need an editor to create some vCard-files. The current source can export vcf-files in a very uncomfortable way and wrong format, so I have to edit each of them anyway. So I want to write them new, it's faster. But I need a program (gratis) to do this.
You can use Thunderbird with MoreFunctionsForAddressBook addon for this.
Another solution is DoubleContact
