Sometimes the simplest tips are the most helpful ones, and that’s certainly the case with today’s, which will show you how to enable orientation lock on your iPhone, iPod touch, and iPad.
iPad’s Orientation Lock Switch Repurposed To Mute In iOS 4.2
There’s an interesting change in the way iOS 4.2 handles orientation lock on the iPad… one that indicates a curious design backpedal on the part of Cupertino.
Previously, orientation lock on the iPad was handled with a physical hardware switch on the side of the device, but in iOS 4.2, it has been repurposed as a physical “Mute” button, with the orientation lock achieved the same way it is on the iPhone 4 or iPod Touch under iOS 4: through the multitasking tray.
It’s a minor but significant change that, I suspect, portends the elimination of the mute/screen orientation button on the second-generation iPad. For famously minimal and streamlined Apple, a physical mute button doesn’t make a lot of sense on an iOS device that isn’t a phone.
