Sync’ing Google Calendar directly to Windows Mobile direct to ‘

Samsung Blackjack II
My wife and I use Google Calendar to stay on top of our personal and business appointments/tasks, etc. b/c it integrates well with G-mail and Google Docs and it allows us to share multiple calendars (we share three – one for PolyPlat Records/State of Man, one for her and one for me).
She recently got a Samsung Blackjack II to replace her old AT&T phone, so I hit the internet to find a way to sync her Windows Mobile calendar to Google without using Outlook on her PC.
Here are the options I’ve found (feel free to send your updates and I’ll add to the list):
- OggSync http://oggsync.com/ ()
- GooSync http://www.goosync.com ()
- GMobileSync http://rareedge.com/gmobilesync/ ()
