iOS 4.2 GM brings a volume slider widget to the iPhone and iPod touch, just like beta 1 did for iPad. Since iPhone and iPod touch have a no landscape view for home screen, and much narrower screen real estate in general, the volume slider isn't next to the other widgets like it is on iPad, and there's no brightness slider to go with it, but here's what you do get:
- Double tap to open the multitasking fast app switcher dock
- Swipe left to move to the music controls and orientation lock widgets
- Swipe left again to move to the volume slider widgets
