Apple has revealed over 60 sessions it has planned for WWDC in June.

WWDC this year will offer developers in-depth information on Mac OS X Leopard and the iPhone OS, including a dedicated iPhone track for the very first time. Developers who plan attending the show already expect numbers to be up on previous years as a new influx of iPhone developers visit WWDC for the first time.

In-depth technical sessions, hands-on labs and social sessions will all feature at this year's developer event.

Among other topics, these sessions include one called, "Enhancing Your iPhone Web Application with CSS Transforms and Animations", suggesting that the Safari browser that's built-into the iPhone is about to be updated to Safari 3.1, which offers these new features.

The iPhone track also includes sessions on Core Animation and Address Book for iPhone. Contact information until now has been nested inside the Phone menu of the device, though recent reports now indicate that Apple may include a dedicated address book in the device, which will make such information available for use by other applications, presumably.

Back to the Mac, sessions cover the gamut - Cocoa, Core Animation, user interfaces, iCal and CalDAV all get the Apple treatment, and with many more sessions still to be announced, developers are already full of expectation for this year's show.
