Apple revealed several new features of iPhone OS 3.0 at WWDC today. One of these features is “Find My iPhone,” and it is only available to Mobile Me subscribers. However, the Mobile Me page includes a few other “Coming Soon” features that didn’t make it into the Keynote.

Mac OS X 10.5.5 has been released and is available via the Software Update function.

The release notes outline updates to Address Book, Disk Utility and Directory Utility, iCal, Mobile Me, Mail, and Time Machine. Other general fixes are included.
