Split multi-contact .vcf address book into individual .vcf’s

Moving contacts from one phone to another is a tricky business. And when the manufacturers of the said two phones are different, this process quickly turns into a pain in the b**t.

It’s a known fact that Android (and, weirdly, older Sony-Ericsson) phones export their contacts as a single multi-contact vcf file. And it’s also a know (and hated) fact that Nokia’s (otherwise great) Suite program can only import single-contact vCards.
