Long-overdue features of iPhone OS 4 revealed

Secrets are revealed with Apple's release of beta 3 of the upcoming iPhone OS 4.0, and we'll show you screen shots in the gallery below. The biggest surprise? The ability to transfer files from the iPhone to your computer. Damn. That's something the iPhone should have had on day one.

Another change is an easier way to close applications when using the iPhone OS 4.0's new multitasking capability. And iPad users will recognize Orientation Lock, handy for those times you're looking directly down on the iPhone when using it. Yes, I mean when you're reading on the toilet.

Update: Oh, and here's another surprise — there's a pretty good chance of 720p video shooting.
