Conversion of bm3 files to vcard file format

BM3 files come from some older Sony Ericsson phone devices, which means that it should be possible to export contacts to at least CSV format using the Sony Ericsson PC Suite or through some contact synchronization service. Once you have that .csv file, it should be simple enough to use one of the CSV to VCF converters to get your vCard file.
