With the release of the beta 3 of iPhone 4.0 this morning, one of the new major enhancements is the included orientation lock and iPod widget controls.
The new controls are accessed via the multi-tasking interface of firmware 4.0 which is done by pushing the home button twice. Now, instead of just closing applications in the multi-tasking pane, users can swipe leftward and see the new iPod controls and orientation lock.
The iPod controls include the iPod app icon to access the iPod app, a pause/play button, and fast forward/rewind controls. The orientation lock button provides similar functionality as that found on the Apple iPad which simply locks the screen in portrait mode and prevents the display from rotating into landscape. Users can tap the icon again to unlock the orientation lock.
As firmware 4.0 is continually developed, users may see more of these types of mobile widgets.
