As part of the iPhone 3.0 Preview Event today, Apple announced that their iPhone OS, which powers both the iPhone and the iPod touch, is now on 30 million devices -- including 17 million iPhones (presumable 2G and 3G) by December, 2008. And while we're admittedly mathlexic around here, but that sounds like the first admission of iPod touch sales to us, which would peg them at 13 million?

Along with previous stats that have been guestimated (like 25,000 apps in the App Store), Apple also announced over 800 million app downloads (!!) to date, and 800,000 iPhone SDK downloads as well.

Staggering. Numbers. Indeed.
