Sure. How would you like to get the contacts?
I'v tracked down at least part of the issue, some of the contacts had invalid vCard data
(created by SOGo connector). Where it would put something like the following:
..normal vcard stuff..
NOTE: blah blah blah/r/n
/r/n
more blah blah/r/n
even more blah/r/n
..normal vcard ending stuff..
The lines on their own after NOTE were being seen as invalid vCard fields, which seems
to confuse the iPhone a lot, such that it seems to not download other valid cards past the
first broken one perhaps? Difficult to tell, but there were only around 100 with these invalid
cards and the phone was missing around 1000. Once correcting these the phone did
download the full contact list.
Perhaps DAViCal needs to validate the vCards?
There still seems to be a problem in that it takes an excessive amount of time for the phone
to refresh the contacts. Maybe that is something to do with the iOS app, but none of the cards
have images, there should be very little data to transfer really, and once downloaded it
should only be checking for updates?
Any way while its checking it seems the contacts app will not start up and I think choosing to
add a contact from data in another app (like messages) will also not work, it just hangs.
I guess I can try to get a dump of what it actually does when updating..
