Safari in iOS 6 has a full-screen mode on iPhone

One detail Apple publicized at its iPhone 5 event this week is that Safari in iOS 6 now has a full-screen mode. When you switch to landscape mode, Safari’s bottom toolbar will reveal a full-screen button. Tap it and Safari hides its address bar, toolbar, and all buttons but three: back, forward (if necessary), and the full-screen toggle.
