The stream is said to provide developers and users alike an outline of the future for the iPhone.
Apple's Thursday event addressed the version 2.0 software and SDK for the iPhone and iPod touch. Both upgrades allow third-party developers to make native software available for the iPhone and also add enterprise support, including full Microsoft Exchange e-mail.
The presentation also addressed the first clear third-party software announcements from some of Apple's partners, including games from Electronic Arts and SEGA, as well as instant messaging from AOL.
Also unveiled was Apple's App Store, which will serve as the sole download source for publicly available third-party software.
