iPad OS 4.2 'Orientation Lock' to 'Mute Switch' Change Permanent

Before iPad was released, Apple had announced that the hardware switch on the side of the iPad would be a mute switch, just like on the iPhone. But in March the company changed its plans. The mute-switched button was transformed into an orientation-lock. And now, it seems that Apple decided again to change the switch’s purpose via a software update. In new iOS 4.2, expected to be released in November, the orientation-lock button will be transformed again into a mute-switch. You’ll be able to lock screen orientation via a menu to the left of the multitasking dock.

If it is so simple for Apple to change button purpose via software update, why the company would not let its user choose the option themselves. But Apple isn’t planning to make that a changeable option, Steve Jobs confirmed this info.
