9to5Mac reports that new features have been added to the iPhone's multitasking bar as of the release of iPhone OS 4 beta 3 earlier today. Swiping left from the multitasking bar now accesses a new set of controls. On the far left is an orientation lock, which disables the iPhone's auto-switching between portrait and landscape orientation. This achieves via software the same thing as the iPad's dedicated orientation lock hardware switch. It will make using the iPhone in a reclined position much easier; no longer will the iPhone switch between orientations seemingly at random as you're catching up on e-mails just after waking up. And there was much rejoicing.
To the right of the orientation lock is a set of three controls for play/pause and track skipping in the iPod app, as well as a dedicated icon for the app itself. It seems likely this will replace the current "notification window" method for accessing iPod controls via a double-tap of the Home button.
Cool bit of functionality coming soon in the iPhone OS 4.0 release.
