Odd.  I could have sworn that was from Horde to the client.  Basically, when I removed Funambol from the device the contacts list on the phone was emptied.  I waited 3 hours and nothing was synched from Horde to the device (as I would have expected and as was the case with the calendar).  In an effort to prompt it, I created a test contact on the phone (just a name, no number, no DoB, no email) and waited for it to be synched to Horde.  After 2 hours - nada.  Since I needed my contacts, I reloaded them (under the Activesync account) from an vcard I have on the device SD card...

..  The caveat is that vcard on the SD card is a direct export from Horde... 

Not saying that Horde isn't doing what it should be - but I have a standard OG Droid - have you heard of an issue where it doesn't send the date in UTC?  Since the only dates in the contact forms (and in the logs) that I can see are birthdates - i.e. 1964-01-01 - I'm not sure how to address this.

How do I debug that?  I mean ever since I installed H4 and imported the data from the H3 DB and updates the schemas everything has worked fine.  I can see my default address book, add, edit and delete with no issue.  I have only one address book, so I can't really see how anything can be pointing to something else.  I could reimport the data (from the vcard above) and overwrite the address book if you think that would help..

This is what I have at the moment - I believe they're the defaults.

$conf['activesync']['ping']['heartbeatmin'] = 60;
$conf['activesync']['ping']['heartbeatmax'] = 2700;
$conf['activesync']['ping']['heartbeatdefault'] = 480;
$conf['activesync']['ping']['deviceping'] = true;
$conf['activesync']['ping']['waitinterval'] = 5;

Would these be sensible options?
$conf['activesync']['ping']['heartbeatmin'] = 600;
$conf['activesync']['ping']['heartbeatmax'] = 2700;
$conf['activesync']['ping']['heartbeatdefault'] = 1200;
$conf['activesync']['ping']['deviceping'] = true
$conf['activesync']['ping']['waitinterval'] = 120;

I'm not sure I understand what each parameter does - my choices might reflect that :)
