Engadget is reporting that Apple will be hosting a media event on Tuesday, March 17th to demonstrate iPhone OS 3.0, the next major upgrade to the iPhone OS (firmware). Apple will also provide details on the new SDK (Software Development Kit) to help developers in creating applications for the new operating system.

Apple’s calling this an “advance preview of what we’re building,” so we’re not expecting anything ready to go as of the 17th, but hopefully this will allow developers to start building toward future functionality (hey, how about some push notifications?), and presumably users won’t have too many months to wait after that for the real deal.

Apple previously hosted a media event for iPhone’s “roadmap” and it appears this upcoming event will follow the same theme. The event is scheduled for 10 AM Pacific in the Town Hall auditorium on the company’s campus in Cupertino, CA.
