The Apple iPad has a switch on the side which was originally designed to lock the screen orientation so that your screen wouldn’t keep flipping while you were trying to hold the iPad and read a book or web site in bed. But when Apple launched iOS 4.2 for the iPad recently, the software update changed that button from a screen lock button to a mute button.
You can still lock the screen orientation, but you have to double-click the home button, drag the taskbar to the right, and hit an on-screen lock icon. It’s not nearly as convenient.
Many users preferred the old system, but Apple doesn’t officially let users remap button functions. That’s where third party apps for jailbroken devices come in, and developer Nicolas Haunold has been kind enough to write an app called NoMute. It’s available as a free download from the Cydia store for apps that run on jailbroken iPhones, iPads, and iPods touch.
As you’d expect from the name, NoMute does one thing: It switches the Mute button on iPads running iOS 4.2 back into a screen orientation button.
If you’ve already jailbroken your iPad, you’re good to go. If not, you can use the redsn0w tool to get started.
