I have been trying to get my E-TEN M600 to sync with Mozillas calender Sunbird and the address book in Thunderbird for some time now. Since the M600 uses Windows Mobile 5 it wants to sync with Microsoft Outlook, but i want to keep on using the tools that i prefer, instead of having Microsoft telling me what to use. My first atempt was to create a SyncML solution using Sync4j but that just wouldn't work. I'll write that up to my lacking knowledge of Tomcat but also to the bad documentation available. So, my next stop was FinchSync, it aint as multipurpose as a SyncML solution, but on the other hand it gets the job done.
