Hi,
I've been playing with PortableContacts, and just discovered that some
contacts (those without email addresses, or without emails already
associated with Google) don't come with a unique ID. This was
reported a while ago in the old forum, but never answered:

Apparently the Portable Contacts spec states that all records must
have a unique ID; this is certainly inconvenient, though not fatal to
what I'm doing. Still, I thought it was worth bringing up again in
case it's fixable.
Thanks!
Alex
