Not sure if this qualifies as hardware or software.
Steve must be loosing his mind. I hate when I am trying to read a book or look at a movie and the screen starts flipping around because I accidentally move my hand the wrong way. I liked the screen lock and I keep it on most of the time. I don't want my screen flipping every which way while I am trying to read something just because I tilt my hand a little. Apparently, they want to turn it into a mute button. I'm like why? There is already volume controls right under the screen lock. I think I'll just stick with my iOS 3.2 for Ipad. I liked the screen lock personally. Sorry if this is already posted. I need a way to lock my screen in landscape mode or portrait mode without having to leave the app i am in to get to that mode. Sheeesh!
