I’d like to suggest checking out nuevasync.com, as I just read about it in the apple.com discussion forums: http://discussions.apple.com/thread.jspa?threadID=1604791.
Seems as though several people have had success configuring their iPhone 3G to allow for over-the-air syncing with their Google Calendar…. for free. While not a MobileMe killer (and they’re doing fine hindering themselves at the moment), if a product like this were to gain more traction/support/exposure, it would certainly keep people like me using Google and all it’s services…. not to mention, handing over my gmail userid/password to create a nuevasync account of my own.
Currently I don’t know much about them, and thought if a group as highly-visible as TechCrunch did some investigation and a write-up, it’d be worth considering signing up during their beta.
Keep up the good work guys!
Update: I received a prompt email response from Calley Nye at TechCrunch: Thanks. I’ll look into it.
