Developers installing the Apple iPhone OS 4 beta 3 found an interesting little surprise: iPod controls and an orientation lock in the mult-task app switcher.
The iPod controls are accessed by swiping to the far left.
Apple pulled the beta soon after it went live but has apparently relented, as reports are coming in that it was first up via URL hack, then later back up for everyone.
This is pretty cool stuff, and makes us hunger for the 4.0 all the more. May be time to re-up my developer account.
