Apple announced on Tuesday that a team of executives, led by Steve Jobs, will kick off the companyis annual Worldwide Developers Conference (WWDC) on June 9 at 10:00 AM PDT. In addition, Apple said that this yearis WWDC will showcase OS X Leopard and OS X iPhone.

"The five-day WWDC event, which runs from June 9 to June 13, will feature the first ever iPhone track for mobile developers with in-depth sessions and hands-on labs to fully explore the capabilities of the OS X iPhone 2.0 software, including the iPhone SDK and the App Store, a breakthrough way for developers to wirelessly deliver their applications to iPhone and iPod® touch users," Apple said.

This yearis WWDC will have over 150 sessions that will cover Apple technologies key to Apple developers. Developers will also be able to work one-on-one with Apple engineers in lab sessions.

The annual special events, a Welcome Reception, Apple Design Awards, Lunchtime Speakers and Stump the Experts were reaffirmed.

The Apple announcement appears to establish a new nomenclature for Apple OS products. In the past, Appleis (mostly) FreeBSD UNIX OS + GUI was coined "Mac OS X," a string of characters that still seems to baffle some publications. However, now Apple has used the new terms "OS X Leopard" and "OS X iPhone" which emphasizes and clarifies the naming of the OS for the two devices.
