Anyone know other SyncML clients for Windows Mobile?

[supra2800]

I have a Windows Mobile 6 Smartphone and been using Synthesis SyncML 3.0.0. standard for a week or so, and it worked fine the first few syncs with ZYB.com

Now SyncML just displays "invalid data" whenever I try to sync, both with standard and pro version. So no chance I'm gonna buy this program, unless this "invalid data" issue fixes itself


So, anyone know of other SyncML clients for Windows Mobile devices, so I can sync my calendar?

Thanks.
