Convert BBB to SPB

There doesn't seem to exist any converter that could directly convert data from BlackBerry backups (.bbb) to Samsung backups (.spb). If you are looking for a way to transfer contacts from one device to another (BlackBerry to Android), the best course of action would be to first convert bbb to vcf (which will export your contacts to a vCard file) and then use any of the available vcf to spb conversion solutions to import your contacts back to a Samsung format. Such contacts transfer is usually needed when dealing with older devices as nowadays contacts are usually synced via Gmail or something similar.
