This is a really good synchronisation program that I use to sync my Google Calendars with my mobile phone. I am using a HTC Touch Dual phone right now, Windows Mobile 6 based device and it doubles as my PDA and emergency surf tool.
This synchronisation works with most modern phones and you can log on and check if your model is supported. Configuration is simple and works great so finally I can use google calendar seriously.
Never miss that photo event again! Sync, sync, sync!
