OK, it doesn't really matter I suppose. I just think it's pretty silly to have that slider be ONLY a mute switch. Previously, it was to lock the screen's rotation, which is WAY more useful. First of all, why doesn't Apple let the user decide what that switch should do? See, this is a very good example of Apple just going a little too far with their nazi control. Who is Apple to decide what that switch should be for ALL users??
What's even more ludicrous is that Apple decides to change the function of that physical slider at a whim. Just whenever they feel like it. In iOS v4.1, that slider was a screen-lock (you can prevent the screen from automatically rotating when you rotate the device physically; it's useful in my case in the car when the ipad is on the seat and you don't want the view to keep rotating around as it slides around the seat). In iOS v4.2 that switch is now a mute-lock. What?? And when they changed it, they didn't allow an option to select one or the other. It's pretty insanely retarded behavior. Not only do they not let the user decide what they prefer it to do, but they get them used to one way, and then change it in the next minor update. Wow. Stuff like that makes my jailbreak-nerve to tickle.
