Free/opensource Thunderbird Windows Mobile sync solutions?

Hi Guys,

I'm again in a position where I'm unable to sync my calendar and contacts between my desktop and windows mobile phone and was hoping that someone here has a slick solution that would work for someone that's tired of fiddling to get things working...

I used to use active sync to keep my phone in sync with Outlook and would then occasionally export my contacts manually and tried to stop using calendar, but that was obviously not the best solution.

Then I found a utility "TBExport" which would simply create a .csv file that I can use to replace my Thunderbird contacts (my phone is the master for most calendar and contact data)

A better solution was finchsync which allowed me to sync my mobile directly with Thunderbird, but it was easy to break causing you to delve into the Thunderbird .ics file to fix things. It also did not supported birthday reminders set by TB extentions.

So, then I tried going via google calendar with the Provider and Zimbus extentions but is quite limited and does not support the rich mobile outlook address book. Also most of the utilities focusses on OTA (Over the air) technologies and does not take advantage of wi-fi connections. OggSync is fine for calendar but only syncs contacts on the pro/paid version. Many other utilities assumes google to be the master, totally ignoring the fact that the mobile could be the master. Assuming I can get my calendar in Lightning and sync it to GCal, the utilities does not provide an option to delete the target calender items first.

Anyway, I'm at my wit's end and am hoping someone here has a solution.

First price would be something that sync's Pocket Outlook and Thunderbird/Lightning directly via wi-fi.

Second price would be using a 3rd party web service similar to Plaxo/OggSync but something that that is open source and also plays well with PortableApps.

Thanks
Paul
