Many IPad owners have become largely dissatisfied with the new IOS 4.2 update on their devices. It has turned the lock button on the top into a mute button. Many of us may be confused that we must now that we must go through a very annoying process in order to lock our IPad. We must not double tap the home button, swipe left, and then tap to lock their IPad. I personally feel that this is something that users can deal with with the volume rocker switch. The lock button was a much better feature, and despite Apple’s claims that this is to help with multitasking people are already used to it as a lock switch so why change it now. I would suggest everyone get on their computers as soon as they can and complain if this is an issue for you.
