The first beta version of iOS 4.2 released last month changed the behaviour of the orientation lock switch to act as a mute switch instead, similar to the function of the switch on the iPhone. When this change was first revealed, many wondered if this was intentional behaviour on Apple’s part or simply a temporary change as a result of unifying iOS 4.2 on both the iPhone and iPad devices. 9to5Mac is now reporting that this is an intentional change on Apple’s part following an e-mail exchange between a reader and Steve Jobs. Not only did Jobs allegedly confirm that the switch is going to be used to mute the sound but also indicated that the switch function would not be configurable by the user. It is worth noting that the hardware switch on the iPad was originally advertised as a mute switch, and Apple only changed the function to an orientation lock in late March shortly before the initial release of the iPad. iOS 4.2 on the iPad is expected to include an orientation lock button in the multitasking dock widget that was introduced for the iPhone and iPod touch in iOS 4.0, a function that was not otherwise available on the iPad with iOS 3.2.
