Try awk.

vcf.awk:
/END:/ { # end of vcard
vcard = vcard $0;
print vcard >filename;
vcard = "";
next;
}
{ # append line to vcard
vcard = vcard $0 "\n";
}
/^N:/ { # N:LastName;FirstName;;;
n = split($0,a,":");
n = split(a[2],b,";");
filename = b[1] "-" b[2] ".vcf";
}

and then
awk -f vcf.awk vcffile
