So if you’re an iPhone user, you want contact and calendar syncing over-the-air, you don’t want to pay for Mobileme, and you think Microsoft Exchange server sucks, then you’re just like me and there’s a great solution out there for you: Google Sync.  It supports syncing (manual, fetch or push) contacts list and up to 5 calendars via an ActiveSync protocol.  Mail is coming soon (but you can still use IMAP or POP, so I’m content to wait).  Google Sync is currently in beta, but google betas are fairly stable, and you should have started backing up your data years ago so as to never be totally caught off guard again, so I wouldn’t worry too much.  I’ve been using Google Sync for several weeks now and I’m loving it.
