Yes! Success! Finally.

Another 50 or so failed test imports, three more bugs found, and it's done.

- For some reason, some accented characters (like e accent acute) slip through Yahoo's export filter without being translated to UTF-8 representation - apparently there's some disagreement about whether this is required. They cause gpe Contacts to choke on the file.

- Yahoo exports the Birthday field with only a single digit (no leading zero) for single-digit months and days. I count that as a silly bug in Yahoo's exporter. But gpe Contacts, instead of ignoring the field or misreading it, chokes on the file.

- My Yahoo Contacts list has managed somehow to accumulate a few Yahoo Messenger ID entries which have only a messenger ID and no name field. For these entries Yahoo exports a vCard with no name fields. That of course causes gpe Contacts to choke on the file.

After fixing these 10 or so errors/incompatibilities in the Yahoo Contacts vcf export file, the entire file with about 300 contacts imports successfully to gpe Contacts on the N800.
