If you do a lot of heavy browsing on your iPhone, you'll love this hidden little shortcut in iOS 6. In Safari, just press and hold on the back button to view a list of recently visited pages.
This feature already exists in many third party browsers (and in Safari on the iPad), but when it comes to Safari on the iPhone, this is brand new for iOS 6, and we didn't know about it until today. Give it a try on your iPhone and see how it works -- it's certainly a faster way to view your history and access those old pages. Hit the link for a few other handy iOS 6 shortcuts.
