I'm using BirdieSync with a german "T-Mobile MDA II" wich is basically a branded HTC Himalaya, if I'm not mistaken. My system configuration is as follows:
- Windows Vista 64bit
- The Vista Synchronization Center-Software
- BirdieSync for synchronization with Thunderbird
- MyMobiler (ver 1.21)
- T-Mobile MDAII via USB
If one connects the PocketPC and then starts MyMobiler (a "RemoteDesktop" tool for PPC, check the link above) BEFORE the synchronization with BirdieSync was complete and finished, it might happen that the PocketPC freezes in a way that you can only resurrect it by removing and reinserting the battery (no softreset, and I even could not use the hard-reset button combination). When it's rebootet, all data in volatile memory is lost like after a hard reset, and all Software + Data need to be reinstalled afterwards.
I don't know if the issue lies with BirdieSync or MyMobiler, and when MyMobiler is used AFTER synchronization, I never had any issues at all. But if one forgets to wait for the end of synchronization, this severe error may occur.
Again, I do not know if the problem is BirdieSync or MyMobiler (I reported it to the MyMobiler staff as well), but perhaps it might be something worth looking at
Besides all that, BirdieSync runs like a charm and I definitely did the right thing with registering it
