I test a lot of Windows Mobile phones and a good way to sync them with my Mac would be welcome.  There are some commercial applications that will do this but a free solution would be pretty cool.  Enter SyncMate from Eltima that will sync a long list of data types between the Mac and the Windows Mobile phone.  The free version is pretty functional but a commercial "expert" edition will set you back $39.95 but adds some unique sync capabilities, including iTunes library syncing.  Sure you won’t be playing your DRM-protected iTunes music on Windows Mobile but the rest will do.

I haven’t used SyncMate myself but will likely give it a try due to all the various information it syncs between the two platforms, including contacts, calendar (Entourage and Google supported) and SMS messages.  The paid version adds quite a bit of functionality I haven’t seen in other sync solutions in addition to the iTunes syncing.  Syncing in both versions can be done through a USB connection or via WiFi, something Microsoft saw fit to remove in Windows Mobile 6.  If you try SyncMate share your thoughts with everyone here.
