Apple Thoughts: Over the Air Sync With Google

"On Monday, Google announced that it'd now be offering over-the-air synchronization of Google contacts and calendars with the iPhone, iPod touch, Windows Mobile-based phones, and SyncML-compatible devices."

If you don't have Mobile Me, and have been syncing your iPhone with your Google Calendar the old school way via direct connection with your computer, this might be a good option for you. It is a beta, and currently only allows syncing contacts and calendars, so your mail still has to be handled separately via IMAP or POP. Also, there are known limitations with the iPhone so Google has created a site that lists them.

I have Mobile Me, have for years, and I've finally gotten it to where it works pretty well for me so I won't be changing it up by switching. However, if I didn't have Mobile Me and wanted to wirelessly sync my contacts and calendars, I would probably give this a try.
