As I have mentioned before, I have been playing with solutions to get my Google Calendars to sync with my iPhone. I had settled on using NuevaSync to sync calendar events wirelessly to my phone. I have gotten fed up with the fact that on my phone, all of the calendars got merged, so it is hard to look at events.
On my wife's computer, I had installed OggSync. This syncs her calendar to Outlook. Then from there, the calendars will can be sync'd to Mobile Me.
Yesterday, I found SyncMyCal. This essentially has the same functionality as OggSync, but it seems more polished. Both offer free and paid vesions. I installed it on my computer, and it works well. I think that I will uninstall OggSync from my wife's computer and install
