As we have already covered in an earlier post that the IOS 4.2 update we have lost the orientation lock button on the top of devices, and it has become a mute button. Unfortunately there are not really many options to fix this aside from jail breaking your device. It is not necessarily what Apple had in mind, but there is no software fix for this in sight at the moment. Since this is the case if you want your orientation lock button back then you will have to jailbreak your IPad and go to the app repository known as Cydia and download the NoMute App. It seems it isn’t true for Apple’s slogan of “We have an app for that,” since they certainly do not have an app for this.
