It's not out for the public yet, and we still don't know when it will come, but the Gold Master for Apple's iOS 4.2 became available this week. Apple is still mum on the official features list, but we found a lot of new goodies after we downloaded and installed the developer version on the iPhone 4. The iPad will get additional changes from iOS 4.2, which we've covered in a separate photo gallery.
Nothing is particularly Earth-shattering, but we welcome the updates in any case. You'll find interface tweaks, new personalization options, and added functionality.
First, off is a new master volume control that's accessible from the Home screen. To get there, double tap the home button to get the standard multitasking menu. Then, if you swipe all the way to the left (past the iPod controls), you'll see a new master volume control.
