Conversion of spd files to vcf file format

It doesn't look like that it is feasible to somehow convert or export any .spd files to VCF contacts format. However, it may be possible that you were in fact looking for spb to vcf conversion, i.e. for a way how to export the contacts out of Samsung Kies .spb files and save them in vCard VCF format.
