I know it's hard to wrap your head around the fact that the SDK may soon be here. So don't take our word for it, take Apple's. The invite reads:

Please join us to learn about the iPhone software roadmap, including the iPhone SDK and some exciting new enterprise features.

The SDK was supposed to ship this month, but obviously Apple couldn't get it out the door in time. Whether or not Apple actually rolls out the SDK next week isn't clear, however.

At the least, we should finally receive some details about how Apple plans to handle the development and distribution of native third-party applications—those that run on the iPhone itself and not through the Safari Web browser.

It's also about time Apple started to take the enterprise as seriously as consumer for the iPhone. While it's clear business people and IT pros alike are excited it, very few are likely to make it their primary smartphone due to a lack of enterprise-ready features.

Depending on what direction Apple goes with the SDK, maybe it'll even allow companies to create their own internal iPhone apps, as they can today with most other smartphone platforms.
