Before I switch to the iPhone 3GS, I'd like some syncing advice:

My wife and I for years have shared key events with other on our Palm Tungsten E2's. Just manual beaming of a few events.

Is there some way we can continue doing that when I switch to an iPhone? She syncs her 755P at work to her Outlook calendar on a PC, then beams me calendar events at home as needed.

I don't think we want to completely sync everything between the iPhone and her Treo.

Thanks for your help, all!
