Debugged the ebook backend for the single-telephone-number issue. There seems to be a misunderstanding between the obexd ebook plugin and libebook in maemo on how multiple values for e.g. telephone numbers (work, private, etc) are to be grouped in the vcard.

Still debugging the root cause, but compiled an ugly workaround to use in the meantime. It's attached as obexd.gz. Ungzip and place in /usr/lib/obex/. Then reboot your phone (note that instead of rebooting it's possible to open x-terminal, kill the obexd process and the start it with the commandline parameters listed in /usr/share/dbus-1/services/obexd.service).

With the workaround, my carkit/carkit version (Peugeot Connect Nav in a 5008 delivered a few weeks ago) lists 2 contacts for every single telephone number contact in the N900, and 4 contacts for every two-telephone number contact in the N900.

I noticed the pbab specs require that multiple entries in a vcard require a prefix (A.N, B.N, ...., A.TEL, B.TEL, ...) and the current implementation lacks that prefix, possibly causing the (quad)duple contact issue in my carkit. Appreciate feedback on how your carkit handles it.
